Abstract

Display device, including: substrates, color filters having first and second color filters, drain and gate signal lines (of light blocking material), wherein, an overlapping portion adjacent the first and second color filter overlap, is formed on a region with one of the drain or gate signal lines, a first color filter edge is a first taper and a second color filter edge is a second taper, in the overlapping portion, the first taper is closer to the drain or gate signal line than the second taper in the overlapping portion, the first taper angle is 45° or more and 90° or less corresponding to a surface of the drain or gate signal line, the second taper angle is 45° or more and 90° or less corresponding to a surface of the first taper and, the first taper angle is larger than the second taper angle.

Dependent claims

A display device, comprising:

a pair of substrates,
color filters having a first color filter and a second color filter, drain signal lines, gate signal lines, and a pixel region disposed between the pair of substrates, wherein,
the gate signal lines is made of a light blocking material, and the drain signal line is made of a light blocking material, and
an overlapping portion in which the first color filter overlaps with the second color filter, is formed on one of the drain signal lines or one of the gate signal lines,
an edge portion of the first color filter is a first taper in the overlapping portion, and an edge portion of the second color filter is a second taper in the overlapping portion,
the first taper is closer to the drain signal line or the gate signal line than the second taper in the overlapping portion,
an angle of the first taper is 45° or more and 90° or less corresponding to a surface of the drain signal line or the gate signal line, an angle of the second taper is 45° or more and 90° or less corresponding to a surface of the first taper and,
the angle of the first taper is larger than the angle of the second taper.
