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 (45)

1. A display device comprising:

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

a counter substrate including a color filter layer, a light shielding layer, an overcoat layer, and first spacers, wherein

the array substrate includes a first area and a second area,

the first area overlaps the counter substrate,

the second area is exposed from the counter substrate,

the counter substrate includes an outer edge that is a border between the first area and the second area,

the light shielding layer surrounds the display area,

the color filter layer includes a first color filter and a second color filter,

the first color filter linearly extends in parallel to the outer edge,

the second color filter linearly extends in parallel to the first color filter,

the first color filter is located between the display area and the second color filter,

the second color filter is located between the first color filter and the outer edge, and

the first spacers are arranged along the outer edge and located above the first color filter and the second color filter.

2. The display device of claim 1 , wherein the first color filter and the second color filter are separated from each other.

3. The display device of claim 2 , wherein

the overcoat layer covers the first color filter and the second color filter, and

the first spacers are in contact with the overcoat layer.

4. The display device of claim 2 , wherein the first color filter and the second color filter are blue color filters.

5. The display device of claim 2 , wherein

the counter substrate further includes a second spacer,

the second spacer linearly extends in parallel to the outer edge, and

the second spacer is located between the display area and the second color filter.

6. The display device of claim 5 , wherein the second spacer does not overlap the color filter layer.

7. The display device of claim 6 , wherein the second spacer overlaps a first removed portion of the light shielding layer.

8. The display device of claim 7 , wherein

a second removed portion of the light shielding layer linearly extends in parallel to the first color filter, and

the second removed portion is located between the first color filter and the second color filter.

9. The display device of claim 2 , wherein

the light shielding layer includes a first slit,

the first silt surrounds the display area, and

one side of the first silt extends linearly in parallel to the second color filter, and

the one side of the first slit is located between the display area and the second color filter.

10. The display device of claim 9 , wherein

the color filter layer includes a blue color filter, and

the one side of the first slit is filled with the blue color filter.

11. The display device of claim 9 , wherein

the color filter layer includes a red color filter, and

the one side of the first slit is filled with the red color filter.

12. The display device of claim 10 , wherein

the light shielding layer further includes a second slit,

the second silt surrounds the first slit, and

one side of the second silt extends linearly in parallel to the outer edge, and

the one side of the second slit is located between the first color filter and the outer edge.

13. The display device of claim 12 , wherein the one side of the second slit is filled with the overcoat layer.
