Liquid crystal display, color filter substrate, and method of

Abstract

A liquid crystal display includes a first substrate having a transparent electrode formed on its surface and a non-aperture portion in its predetermined region, a second substrate separated from and opposed to the first substrate, a member having a color filter function and a transparent electrode formed on the second substrate, a liquid crystal layer sandwiched a between the first and second substrates, and a backlight optical system arranged on the side of the second substrate away from the first substrate. The member having a color filter function is patterned in accordance with the display unit controlled by the two transparent electrodes. This member is a color reflecting layer stack constituted by a stack of a first planar-oriented cholesteric liquid crystal layer having a first chiral pitch and a second planar-oriented cholesteric liquid crystal layer having a second chiral pitch different from the first chiral pitch. This color reflecting layer stack has a three-layered stacked region formed by further stacking a third planar-oriented cholesteric liquid crystal layer having a third chiral pitch different from the first and second chiral pitches. The three-layered stacked region corresponds to the non-aperture portion of the first substrate and has a function of returning light from the non-aperture portion to the backlight optical system.
