Abstract: A liquid crystal display comprising an STN liquid crystal cell (16) positioned at the center and sealing and holding a nematic liquid crystal (6), twist-aligned at 180-270°, between a first substrate (1) having a first electrode (3) and a second substrate (2) having a second electrode (4), a phase plate (13) and an absorption type polarizer plate (8) provided in that order on the outside of the second substrate (2) and a reflection type polarizer plate (10) and a light absorption member (11) provided in that order on the outside of the first substrate (1). With this construction, the display can produce a metallic silver background by the light reflected off the reflection type polarizer plate (10), and black and color images by the light transmitting the reflection type polarizer plate (10) and absorbed by the light absorption member (11) or reflected in only light components of particular colors.

Abstract: A display apparatus includes a display panel receiving light from a light source. The display panel includes a liquid crystal panel, first and second polarizers respectively disposed on front and rear sides of the liquid crystal panel, and an optical layer disposed on a front surface of the second polarizer. The optical layer includes a first resin layer having light absorption portions for absorbing a portion of incident light, a second resin layer disposed on a front surface of the first resin layer, the second resin layer having a higher refractive index than the first resin layer, the second resin layer having light diffusion portions for diffusing light not absorbed by the light absorption portions.
