Abstract:
1. A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal composition layer held between the first substrate and the second substrate, a color filter including a black matrix and an RGB three-color pixel portion, a pixel electrode, and a common electrode, wherein the liquid crystal composition layer is composed of a liquid crystal composition including one or more compounds selected from a compound group represented by General Formula (LC1) to General Formula (LC4): (where R (in these structures, one or more CH wherein,in the RGB three-color pixel portion, an R pixel portion includes, as a coloring material, a diketopyrrolopyrrole-based red pigment having an average primary particle size of 5 to 50 nm as measured by small angle X-ray scattering.
