Abstract

According to an aspect, a display device includes: a display panel including an array substrate, a counter substrate, a liquid crystal layer between the array substrate and the counter substrate, and spacers projecting from the counter substrate toward the array substrate; a light-transmitting glass base member bonded to the display panel; and a light source that includes a light guide provided along a side surface of the array substrate, a side surface of the counter substrate, or a side surface of the glass base member, and light emitters facing the light guide. The array substrate includes: signal lines; scan lines; and switching elements coupled to the scan lines and the signal lines. The spacers are arranged in positions facing the respective switching elements and are provided with adhesion layers provided such that the counter substrate and the array substrate adhere to each other.

Claims (23)

1. A display device comprising:

a display panel comprising:

an array substrate,

a counter substrate,

a liquid crystal layer between the array substrate and the counter substrate,

a plurality of spacers projecting from the counter substrate toward the array substrate, and

a frame surrounding each of the spacers on all four sides;

a light-transmitting glass base member bonded to the display panel; and

a light source that comprises a light guide provided along a side surface of the array substrate, a side surface of the counter substrate, or a side surface of the glass base member, and a plurality of light emitters arranged so as to face the light guide,

wherein the array substrate comprises:

a plurality of signal lines arranged at intervals in a first direction,

a plurality of scan lines arranged at intervals in a second direction, and

a plurality of switching elements coupled to the scan lines and the signal lines,

wherein the spacers are arranged in positions facing the respective switching elements and are provided with adhesion layers provided such that the counter substrate and the array substrate adhere to each other, and

wherein the frame projects from the counter substrate toward the array substrate.

2. The display device according to claim 1 , wherein the adhesion layers are provided at distal ends of all or some of the spacers.

3. The display device according to claim 1 ,

wherein the spacers each comprise a housing having a space inside, and

wherein all or some of the housings are filled with the adhesion layers.
