Abstract

A display component includes a glass substrate GS including a display area AA and a non-display area NAA surrounding the display area AA, a color filter 29 overlapping a surface of the glass substrate GS in the display area AA, a CF board side alignment film 32 disposed in at least the display area AA to cover the color filter 29 and partially including a thickness variation portion 36 that gradually decreases thickness thereof toward an outer side, and a film forming control portion 37 disposed in the non-display area NAA to be next to the display area AA and overlapping the surface of the glass substrate GS and configured to form the CF board side alignment film 32 such that the thickness variation portion 36 is in the non-display area NAA.

First claim

1 . A display component comprising:
a base board including a display area and a non-display area surrounding the display area; a display element overlapping a surface of the base board in the display area; an alignment film disposed in at least the display area and covering the display element and partially including a thickness variation portion that gradually decreases thickness thereof toward an outer side thereof; and a film forming control portion disposed in the non-display area and next to the display area and overlapping the surface of the base board and configured to form the alignment film such that the thickness variation portion is in the non-display area.

2 . The display component according to claim 1 , wherein the film forming control portion surrounds an entire periphery of the display area.

3 . The display component according to claim 2 , wherein the film forming control portion has a surface at a height greater than a height of a surface of the display element.

4 . The display component according to claim 1 , further comprising:
a second base board to be attached to the base board opposite each other with having a clearance therebetween; liquid crystals sandwiched between the base board and the second base board; and a sealing member surrounding the liquid crystals and being between the base board and the second base board and sealing the liquid crystals, wherein the film forming control portion is closer to the display area than the sealing member and spaced from the second base board with having a clearance.

5 . The display component according to claim 1 , further comprising a light blocking portion disposed in at least the non-display area to overlap the surface of the base board and having a height smaller than that of the display element.

6 . The display component according to claim 5 , wherein the film forming control portion is made of a material same as that of the display element and has a thickness equal to that of the display element.

7 . The display component according to claim 5 , wherein
the display element is a color filter that selectively transmits light having a specific wavelength region, and the film forming control portion is made of a material same as that of the color filter.

8 . The display component according to claim 7 , wherein
the color filter includes color portions that are arranged in a matrix with a planar arrangement in the display area, and the film forming control portion is continuous from one of the color portions that is at an edge of the display area.

9 . The display component according to claim 1 , further comprising a light blocking portion disposed in at least the non-display area and overlapping the surface of the base board, wherein
the film forming control portion overlaps the light blocking portion in the non-display area and is made of a material same as that of the light blocking portion.

10 . The display component according to claim 1 , further comprising:
a second base board to be attached to the base board opposite each other with having a clearance therebetween; liquid crystals sandwiched between the base board and the second base board; and a sealing member surrounding the liquid crystals and being between the base board and the second base board and sealing the liquid crystals, wherein the film forming control portion is disposed close to the display area and spaced from the sealing member with having a clearance.

11 . A display device comprising the display component according to claim 1 .

12 . A television device comprising the display device according to claim 11 .
