## Abstract

Aspects disclosed herein relate to a diffuser plate supporter, a backlight unit, and an electronic device, in which a portion configured to support a diffuser plate in a diffuser plate supporter is made of a transparent material and a portion to be fastened to the cover bottom is made of an opaque material, so that the diffuser plate supporter can prevent light leakage from occurring on the back side of the cover bottom without interfering with light reaching the diffuser plate. In addition, through a reinforcement design for the boundary portion between the portion made of the transparent material and the portion made of the opaque material, it is possible to prevent the portions made of different materials from being separated from each other during rotational fastening of the diffusion plate supporter.

## Claims

### Claim 1

A diffuser plate supporter comprising:
a transparent support portion having a protruding shape;
a transparent connection portion extending to a horizontal direction from a lower end portion of the transparent support portion and bent to a vertical direction;
an opaque base having first and second side surfaces and a bottom surface, at least a portion of the first and second side surfaces connected to an end of the connection portion; and
an opaque fastening portion protruding from the bottom surface of the base,
wherein the connection portion encloses at least part of the side surface of the base, and a width of a part of the connection portion which connects the support portion and the base each other is broader than a width of a part of the connection portion which encloses at least part of the side surface of the base.

### Claim 2 (depends on 1)

The diffuser plate supporter of claim 1, wherein the transparent connection portion extends with enclosing a part of the side surface of the opaque base in the portion where the transparent connection portion is connected to the opaque base.

### Claim 3 (depends on 1)

The diffuser plate supporter of claim 1, wherein the transparent connection portion is connected to first and second corresponding side surfaces of the opaque base.

### Claim 4 (depends on 3)

The diffuser plate supporter of claim 3, wherein the first connection portion extends to a first direction and connected to the first side surface of the opaque base and encloses a periphery of the first side surface of the opaque base, and the second connection portion extends in a second direction different from the first direction connected to the second side surface of the opaque base and encloses a periphery of the second side surface of the opaque base.

### Claim 5 (depends on 1)

The diffuser plate supporter of claim 1, wherein the transparent support portion and the opaque base are spaced apart from each other by the transparent connection portion.

### Claim 6

A diffuser plate supporter comprising:
a transparent support portion having a protruding shape;
an opaque base connected to a lower end of the transparent support portion and having an area wider than an area of the lower end of the transparent support portion; and
an opaque fastening portion extended from a bottom surface of the opaque base,
wherein the transparent connection portion is connected to first and second corresponding side surfaces of the opaque base, and
wherein the first connection portion extends to a first direction and connected to the first side surface of the opaque base and encloses a periphery of the first side surface of the opaque base, and the second connection portion extends in a second direction different from the first direction connected to the second side surface of the opaque base and encloses a periphery of the second side surface of the opaque base.

### Claim 7 (depends on 6)

The diffuser plate supporter of claim 6, wherein the opaque base is partially transparent in a portion where the opaque base is connected to the transparent connection portion.

### Claim 8 (depends on 6)

The diffuser plate supporter of claim 6, wherein the transparent connection portion extends with enclosing a part of the side surface of the opaque base in the portion where the transparent connection portion is connected to the opaque base.

### Claim 9 (depends on 6)

The diffuser plate supporter of claim 6, wherein the transparent support portion and the opaque base are spaced apart from each other by the transparent connection portion.

### Claim 10

A backlight unit comprising:
a diffuser plate supporter including,
a transparent support portion having a protruding shape,
a transparent connection portion extending to a horizontal direction from a lower end portion of the transparent support portion and bent to a vertical direction,
an opaque base having first and second side surfaces and a bottom surface, at least a portion of the first and second side surfaces connected to an end of the connection portion, and
an opaque fastening portion protruding from the bottom surface of the base;
a diffuser plate having a bottom surface supported by the diffuser plate supporter; and
a cover bottom accommodating the diffuser plate, the diffuser plate supporter being fastened to the cover bottom,
wherein the transparent connection portion is connected to first and second corresponding side surfaces of the opaque base, and
wherein the first connection portion extends to a first direction and connected to the first side surface of the opaque base and encloses a periphery of the first side surface of the opaque base, and the second connection portion extends in a second direction different from the first direction connected to the second side surface of the opaque base and encloses a periphery of the second side surface of the opaque base.

### Claim 11 (depends on 10)

The backlight unit of claim 10, wherein the cover bottom includes a hole to which the diffuser plate supporter is fastened, and the opaque base is located above the hole.

### Claim 12 (depends on 10)

The diffuser plate supporter of claim 10, wherein the opaque base is partially transparent in a portion where the opaque base is connected to the transparent connection portion.

### Claim 13 (depends on 10)

The diffuser plate supporter of claim 10, wherein the transparent connection portion extends with enclosing a part of the side surface of the opaque base in the portion where the transparent connection portion is connected to the opaque base.

### Claim 14 (depends on 10)

The diffuser plate supporter of claim 10, wherein the transparent support portion and the opaque base are spaced apart from each other by the transparent connection portion.
