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 (63)

1 - 18 . (canceled)

19 . A display device comprising:

a first substrate including pixel electrodes in a display area; and

a second substrate opposed to the first substrate, the second substrate including

a color resist between the first substrate and the second substrate,

a light shielding layer between the first substrate and the second substrate, and

an overcoat layer between the first substrate and the second substrate;

wherein

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

the first slit surrounds at least three sides of the display area,

the second slit is located outside of the first slit, and surrounds at least three sides of the first slit,

the first slit is filled with the color resist, and

the second slit is filled with the overcoat layer.

20 . The display device of claim 19 , wherein

the color resist in the first slit is covered by the overcoat layer.

21 . The display device of claim 20 , wherein

a width of the first slit is larger than a width of the second slit.

22 . The display device of claim 20 , wherein

the color resist in the first slit has a blue color.

23 . The display device of claim 20 , wherein

the color resist in the first slit has a red color.

24 . The display device of claim 20 , wherein

the color resist in the first slit includes stacked color resists having different colors.

25 . The display device of claim 24 , wherein

the stacked color resists include a blue color resist and a red color resist.

26 . The display device of claim 20 , further comprising a polarizing plate on the second substrate, wherein

the first slit overlaps the polarizing plate, and

the second slit does not overlap the polarizing plate.

27 . The display device of claim 20 , further comprising an alignment film on the overcoat layer,

wherein

an edge of the alignment film is located between the second slit and the display area.

28 . The display device of claim 27 , wherein

the edge of the alignment film is located between the second slit and the first slit.

29 . A substrate comprising:

a color resist;

a light shielding layer; and

an overcoat layer covering the light shielding layer;

wherein

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

the first slit surrounds at least three sides of a display area,

the second slit is located outside of the first slit, and surrounds at least three sides of the first slit,

the first slit is filled with the color resist,

the second slit is filled with the overcoat layer,

each of the first slit and the second slit is located outside of the display area,

the first slit is located between the display area and the second slit, and

the second slit is located between an outer end of the substrate and the first slit.

30 . The substrate of claim 29 , wherein

the color resist in the first slit is covered by the overcoat layer.

31 . The substrate of claim 30 , wherein

a width of the first slit is larger than a width of the second slit.

32 . The substrate of claim 30 , wherein

the color resist in the first slit has a blue color.

33 . The substrate of claim 30 , wherein

the color resist in the first slit has a red color.

34 . The substrate of claim 30 , wherein

the color resist in the first slit includes stacked color resists having different colors.

35 . The substrate of claim 34 , wherein

the stacked color resists include a blue color resist and a red color resist.

36 . The substrate of claim 30 , further comprising an alignment film on the overcoat layer,

wherein

an edge of the alignment film is located between the second slit and the display area.

37 . The substrate of claim 36 , wherein

the edge of the alignment film is located between the second slit and the first slit.
