US 2006/0139539 A1 · Multi-domain vertical alignment liquid crystal display which generates circularly polarized light

Abstract

A MVA LCD (Multi-domain Vertical Alignment Liquid Crystal Display) is provided. The MVA LCD includes a first substrate and a second substrate; a common electrode disposed on a first surface of the first substrate; a pixel electrode disposed on a first surface of the second substrate and corresponds to the common electrode; a plurality of liquid crystal molecules filled between the first substrate and the second substrate; a domain regulating means disposed on the first substrate or the second substrate for regulating the LC director of the liquid crystal molecules; a first quarter-wave (¼λ) plate disposed on the top of a second surface of the first substrate; a first linear light polarizer sheet disposed on the top of the first quarter-wave plate; a second quarter-wave plate disposed on the bottom of a second surface of the second substrate; and a second linear light polarizer sheet disposed on the bottom of the second quarter-wave plate. The incident light is in the form of circularly polarized light when transmitted through the liquid crystal molecules of the MVA LCD.
