## Abstract

An exemplary liquid crystal display (LCD) (200) includes an LCD panel (210) including a first glass substrate (212) and a second glass substrate (214) parallel to the first glass substrate; a backlight module (220) includes a frame (222) accommodating the LCD panel; and a fixing member (240) attached to the frame of the backlight module and resiliently holding an end portion of the LCD panel in position in the frame.

## Claims

### Claim 1

A liquid crystal display (LCD) comprising:
an LCD panel comprising a first glass substrate and a second glass substrate parallel to the first glass substrate, the second glass substrate comprising an end portion;
a backlight module comprising a frame accommodating the LCD panel, the frame comprising two side walls at opposite sides thereof, and each side wall comprising a notch near an end thereof and a hook member positioned in the notch; and
a fixing member attached to the frame of the backlight module and resiliently holding the end portion of the second glass substrate in position in the frame, the fixing member pressing on the end portion, the fixing member comprising a main body, two clasping flanges extending from opposite ends of the main body, and a pressing protrusion, the clasping flanges attached to the side walls of the frame, each clasping flange comprising an opening, the clasping flanges being received in the notches with the hook members being engagingly received in the openings, and the main body of the fixing member comprising a first surface and a second surface at opposite sides thereof, the pressing protrusion being formed at the second surface;
wherein the pressing protrusion is elastically deformed and resiliently presses the end portion of the second glass substrate, and the main body further comprises a buffer layer attached on the second surface, the buffer layer defining a window into which the pressing protrusion extends.

### Claim 2 (depends on 1)

The LCD as claimed in claim 1, wherein a distance between the two clasping flanges is substantially the same as a distance between the two hook members.

### Claim 3 (depends on 1)

The LCD as claimed in claim 1, wherein the pressing protrusion is elongated.

### Claim 4 (depends on 1)

The LCD as claimed in claim 1, wherein the pressing protrusion has a generally curved transverse cross-section.

### Claim 5 (depends on 1)

The LCD as claimed in claim 1, wherein the pressing protrusion defines a corresponding indentation at the first surface.

### Claim 6 (depends on 1)

The LCD as claimed in claim 1, wherein the buffer layer is made of elastic material, and the buffer layer is compressed such that a thickness of the buffer layer is substantially the same as a height of the pressing protrusion.

### Claim 7 (depends on 1)

The LCD as claimed in claim 1, wherein the buffer layer is made of foamed plastic.

### Claim 8 (depends on 1)

The LCD as claimed in claim 1, further comprising a protection layer disposed on the end portion of the second glass substrate.

### Claim 9 (depends on 8)

The LCD as claimed in claim 8, wherein the protection layer is made of silica gel.

### Claim 10 (depends on 1)

The LCD as claimed in claim 1, wherein the fixing member is made of metal or plastic.

### Claim 11 (depends on 1)

The LCD as claimed in claim 1, wherein the frame is made of plastic material.

### Claim 12 (depends on 1)

The LCD as claimed in claim 1, further comprising a flexible printed circuit board (FPCB), and a main PCB disposed at a side of the LCD distant from the LCD panel, wherein one terminal of the FPCB is connected to the end portion of the second glass substrate, and another terminal of the FPCB is connected to an edge portion of the main PCB.

### Claim 13 (depends on 12)

The LCD as claimed in claim 12, wherein the backlight module further comprises a first diffusing sheet, a prism sheet, a second diffusing sheet, and a light guide plate, which are accommodated in the frame in that order from top to bottom.

### Claim 14 (depends on 13)

The LCD as claimed in claim 13, wherein the backlight module further comprises a reflective sheet attached to the frame and being positioned adjacent to a bottom of the light guide plate.
