Abstract

Official abstract text for this publication.

According to one embodiment, a display device includes a first substrate, a second substrate opposing the first substrate, a liquid crystal layer and a light source that emits light to the liquid crystal layer, and the first substrate includes a first portion opposing the second substrate and having a first thickness and a second portion not opposing the second substrate and having a second thickness which is less than the first thickness, and the light source is disposed on the second portion, and the light source includes a first surface opposing the second portion and a second surface opposing the first surface, and a wiring substrate is disposed on the second surface so that the wiring substrate does not protrude with respect to the second substrate in a thickness direction.

First claim

Opening claim text (preview).

What is claimed is: 1 . A display device comprising: a first substrate; a second substrate opposing the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; and a light source that emits light to the liquid crystal layer, wherein the first substrate comprises a first portion opposing the second substrate and having a first thickness and a second portion not opposing the second substrate and having a second thickness which is less than the first thickness, the light source is disposed on the second portion, and a wiring substrate is disposed on the second portion so that the light source is between the first substrate and the wiring substrate. 2 . The display device of claim 1 , wherein the wiring substrate does not protrude with respect to the second substrate in a thickness direction. 3 . The display device of claim 1 , wherein the second thickness is less than half of the first thickness. 4 . The display device of claim 1 , wherein the light source emits light to a side surface of the second substrate. 5 . The display device of claim 4 , further comprising: an air layer provided between the light source and the side surface of the second substrate. 6 . The display device of claim 1 , wherein the liquid crystal layer comprises a polymer-dispersed liquid crystal. 7 . A display device comprising: a first substrate; a second substrate opposing the first substrate; a liquid crystal layer disposed between the first substrate and the second substrate; and a light source that emits light to the liquid crystal layer, wherein the first substrate comprises a first portion opposing the second substrate and having a first thickness and a second portion not opposing the second substrate and having a second thickness which is less than the first thickness, the light source is disposed on the second portion, the light source comprises a first surface opposing the second portion and a second surface opposing the first surface, and a third thickness between the first surface and the second surface is larger than a difference between the first thickness and the second thickness. 8 . The display device of claim 7 , further comprising: an air layer provided between the light source and a first side surface, wherein the first side surface is between the first portion and the second portion. 9 . The display device of claim 7 , wherein the light source emits light to a side surface of the second substrate. 10 . The display device of claim 9 , further comprising: an air layer provided between the light source and the side surface of the second substrate. 11 . The display device of claim 7 , wherein the liquid crystal layer comprises a polymer-dispersed liquid crystal.
