Abstract

A liquid crystal display device includes a TFT substrate having a display region where pixels each having a TFT and a pixel electrode are formed in a matrix, a counter substrate having a display region where color filters of three colors are formed in a matrix, the TFT substrate and the counter substrate being bonded together with a sealing material in a seal portion at a periphery, and liquid crystal sealed between the TFT substrate and the counter substrate by the seal material. In the display region, a first insulation film, a first alignment film, a first columnar spacer, an overcoat film, a first color filter among the color filters of three colors are stacked in this order between the TFT substrate and the counter substrate.

Claims (66)

1 . A display device comprising:

a first substrate;

a display region on the first substrate, the display region including a plurality of pixels;

a peripheral region surrounding the display region on the first substrate;

a second substrate opposing the first substrate and including a plurality of color filters;

a sealing material bonding the first substrate and the second substrate; and

a plurality of spacers between the first substrate and the second substrate,

wherein

the plurality of spacers includes a first spacer in the peripheral region,

the plurality of color filters includes a first color filter in the peripheral region,

the first spacer and the first color filter overlap the sealing material in a plan view, and

the first spacer is surrounded by the sealing material in the plan view.

2 . The display device according to claim 1 , wherein

the first color filter overlaps the first spacer in a sectional view.

3 . The display device according to claim 1 , wherein

the plurality of spacers is provided on the second substrate.

4 . The display device according to claim 1 , wherein

the plurality of color filters further includes a second color filter in the display region, and

the first color filter is separated from the second color filter.

5 . The display device according to claim 1 , wherein

the first spacer is provided on the first color filter.

6 . The display device according to claim 1 , wherein

the sealing material is not provided between the first spacer and the first substrate.

7 . The display device according to claim 1 , further comprising:

a protrusion between the first substrate and the second substrate,

wherein

the first color filter is not provided between the protrusion and the second substrate.

8 . The display device according to claim 7 , wherein

the protrusion is provided on the second substrate.

9 . The display device according to claim 7 , wherein

the protrusion surrounds the display region in the plan view.

10 . The display device according to claim 7 , wherein

the sealing material is between the protrusion and the first substrate.

11 . A display device comprising:

a first substrate;

a display region on the first substrate, the display region including a plurality of pixels;

a peripheral region surrounding the display region on the first substrate;

a second substrate opposing the first substrate and including a plurality of color filters;

a sealing material bonding the first substrate and the second substrate; and

a plurality of spacers between the first substrate and the second substrate,

wherein

the plurality of spacers includes a first spacer in the peripheral region,

the plurality of color filters includes a first color filter in the peripheral region,

the first spacer and the first color filter overlap each other in a plan view, and

the sealing material covers an edge of the first color filter.

12 . The display device according to claim 11 , wherein

the first color filter overlaps the first spacer in a sectional view.

13 . The display device according to claim 11 , wherein

the plurality of spacers is provided on the second substrate.

14 . The display device according to claim 11 , wherein

the plurality of color filters further includes a second color filter in the display region, and

the first color filter is separated from the second color filter.

15 . The display device according to claim 11 , wherein

the first spacer is provided on the first color filter.

16 . The display device according to claim 11 , wherein

the sealing material is not provided between the first spacer and the first substrate.

17 . The display device according to claim 11 , further comprising:

a protrusion between the first substrate and the second substrate,

wherein

the first color filter is not provided between the protrusion and the second substrate.

18 . The display device according to claim 17 , wherein

the protrusion is provided on the second substrate.

19 . The display device according to claim 17 , wherein

the protrusion surrounds the display region in the plan view.

20 . The display device according to claim 17 , wherein

the sealing material is between the protrusion and the first substrate.
