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 (57)

1. A display device comprising:

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 pixel 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,
