Abstract

Provided is a display device, in which: a center position of a row-wise width of a black matrix located between a red pixel and a green pixel is displaced toward a red pixel side from the center position of a row-wise line width of a data line overlapping with the black matrix in a plan view; and the center position of the row-wise width of the black matrix located between the green pixel and a blue pixel is displaced toward a blue pixel side from the center position of the row-wise line width of the data line overlapping with the black matrix in a plan view.

Claims (33)

1. A display device, comprising:

a first substrate on a back surface side; and

a second substrate on a display surface side,

the first substrate and the second substrate being opposed to each other,

the first substrate comprising:

a plurality of data lines formed thereon;

a plurality of gate lines formed thereon; and

a plurality of pixel electrodes formed thereon and arranged so as to form an array of pixels aligned in a column direction in which the plurality of data lines extend and in a row direction in which the plurality of gate lines extend,

the second substrate comprising:

a plurality of light transmission portions formed thereon, for transmitting light, and arranged so as to correspond to each of the plurality of pixels; and

a light shielding portion formed thereon, for blocking light from transmitting therethrough, and formed around each of the plurality of light transmission portions,

the plurality of pixels comprising:

a first pixel corresponding to a first light transmission portion for transmitting first color light;

a second pixel corresponding to a second light transmission portion for transmitting second color light; and

a third pixel corresponding to a third light transmission portion for transmitting third color light, wherein:

the pixels aligned in the row direction define pixel groups, in each of which the first pixel, the second pixel, the third pixel, the third pixel, the second pixel, and the first pixel are arrayed in a repeating pattern of the stated order in the row direction, and

a row-wise width of the light shielding portion located between the adjacent two third pixels is smaller than a row-wise width of the light shielding portion located between the third pixel and the second pixel.

2. The display device according to claim 1 , wherein

a row-wise width of the light shielding portion located between the adjacent two first pixels is smaller than a row-wise width of the light shielding portion located between the first pixel and the second pixel.

3. The display device according to claim 1 , wherein

the first pixel is a red pixel corresponding to a red light transmission portion for transmitting red light,

the second pixel is a green pixel corresponding to a green light transmission portion for transmitting green light, and

the third pixel is a blue pixel corresponding to a blue light transmission portion for transmitting blue light.

4. The display device according to claim 1 , wherein

the first pixel is a red pixel corresponding to a red light transmission portion for transmitting red light,

the second pixel is a blue pixel corresponding to a blue light transmission portion for transmitting blue light, and

the third pixel is a green pixel corresponding to a green light transmission portion for transmitting green light.

5. The display device according to claim 1 , wherein

the first pixel is a green pixel corresponding to a green light transmission portion for transmitting green light,

the second pixel is a red pixel corresponding to a red light transmission portion for transmitting red light, and

the third pixel is a blue pixel corresponding to a blue light transmission portion for transmitting blue light.

6. The display device according to claim 2 , wherein

a distance between the adjacent two drain lines located at both sides of the first pixels, a distance between the adjacent two drain lines located at both sides of the second pixels, and a distance between the adjacent two drain lines located at both sides of the third pixels are substantially equal to each other.
