Abstract

According to one embodiment, a display device comprises a display panel and a polarizing plate. The display panel comprises a display area, a non-display area surrounding the display area, and a light-shielding layer arranged in the display area and the non-display area. The polarizing plate is provided on a surface of the display panel, and including an end portion located in the non-display area. In this display device, the light-shielding layer opposite to the end portion of the polarizing plate is at least partially removed.

Claims (50)

1. A display device comprising:

an array substrate including pixel electrodes in a display area; and

a counter substrate including a color resist, a light shielding layer, and an overcoat layer, wherein

the light shielding layer includes a first slit and a second slit,

the first slit surrounds the display area,

the second slit surrounds the first slit,

the first slit is filled with the color resist,

the second slit is filled with the overcoat layer, and

the color resist in the first slit has blue color.

2. The display device of claim 1 , wherein

the display area is rectangular,

the first slit surrounds all circumference of the display area, and

the second slit surrounds all circumference of the first slit.

3. The display device of claim 2 , wherein

the array substrate includes a terminal area,

the terminal area is exposed from an edge of the counter substrate,

an edge of the light shielding layer is between the edge of the counter substrate and the second slit,

the second slit is between the edge of the light shielding layer and the first slit, and

the first slit is between the second slit and the display area.

4. The display device of claim 3 , wherein

the terminal area extends along a first direction,

the first slit includes a first portion and a second portion,

the second slit includes a third portion, a fourth portion, and a connecting portion,

the first portion and the third portion extend in the first direction,

the second portion and the fourth portion extend in a second direction intersecting the first direction,

the first portion and the second portion are orthogonal to each other,

the third portion and the fourth portion are connected by the connecting portion, and

the connecting portion is curved.

5. The display device of claim 1 , wherein

the color resist in the first slit includes a blue color resist and a red color resist stacking each other.

6. The display device of claim 4 , wherein

the color resist in the first slit includes a blue color resist and a red color resist stacking each other.

7. The display device of claim 1 , wherein

the array substrate and the counter substrate are attached by a sealant,

the second slit overlaps with the sealant, and

the first slit does not overlap with the sealant.

8. The display device of claim 7 , wherein

the array substrate includes an organic insulating layer,

the pixel electrodes is above the organic insulating layer,

the organic insulating layer includes a removed portion, and

the removed portion overlaps with the sealant and the second slit.

9. The display device of claim 4 , wherein

the array substrate and the counter substrate are attached by a sealant,

the second slit overlaps with the sealant, and

the first slit does not overlap with the sealant.

10. The display device of claim 9 , wherein

the array substrate includes an organic insulating layer,

the pixel electrodes is above the organic insulating layer,

the organic insulating layer includes a removed portion, and

the removed portion overlaps with the sealant and the second slit.
