Abstract
A liquid crystal display device includes a counter substrate facing an array substrate via a liquid crystal layer, and a backlight unit provided on a back side of the array substrate. The counter substrate includes a first light shielding layer formed on a first transparent substrate, a transparent resin layer formed on the first transparent substrate, and a second light shielding layer formed on the transparent resin layer. The first light shielding layer has openings corresponding to polygonal pixels having a polygonal shape in which at least two edges are parallel in a planar view. The first light shielding layer includes a first linear pattern having a center line that overlaps with a center line of a second linear pattern of the second light shielding layer in a planar view. The first linear pattern has a line width different from a line width of the second linear pattern.
