## Abstract

Light guide structures that include a transparent plate having a first end and a second end; and a plurality of transparent light guide members, each transparent light guide member extending from the first end to the second end along one surface of the transparent plate and being configured to emit white light in response to light applied thereto are described.

## Claims

### Claim at position 1

1-5. (canceled)

### Claim 6

A light guide structure, comprising:
a transparent plate having a first end and a second end;
a plurality of transparent light guide members, each transparent light guide member extending from the first end to the second end along one surface of the transparent plate and being configured to emit white light in response to light applied thereto; and
a plurality of reflection members, each reflection member being arranged between the one surface of the transparent plate and one of the plurality of transparent light guide members and being configured to reflect the applied light so as to direct the applied light to propagate within one of the plurality of transparent light guide members along the one surface of the transparent plate.

### Claim at position 3

7-11. (canceled)

### Claim 12 (depends on 6)

The light guide structure of claim 6, wherein each reflection member has a thickness of less than about 1 micrometre.

### Claim 13

A display device, comprising:
a display panel;
a light source configured to emit light;
a transparent plate having a first end and a second end wherein one surface of the transparent plate faces the display panel; and
a plurality of transparent light guide members, each transparent light guide member extending from the first end to the second end along the one surface of the transparent plate and being configured to emit white light in response to the light applied thereto.

### Claim 14 (depends on 13)

The display device of claim 13, wherein each transparent light guide member contains fluorescent substances to emit the white light in response to the light emitted from the light source.

### Claim 15 (depends on 13)

The display device of claim 13, wherein the display panel is a reflective display panel.

### Claim 16

(canceled)

### Claim 17

(canceled)
