ABSTRACT:
A semitransparent liquid crystal display element comprises a liquid crystal panel composed of a plurality of pixels each having a reflective portion and a transparent portion arranged therein, a first polarizer sheet located on the observer's side of the liquid crystal panel, and a second polarizer sheet located on the opposite side of the liquid crystal panel from the first polarizer sheet, the angle of twist of a liquid crystal molecule which forms each pixel of the liquid crystal panel ranging from 44 degrees to 46 degrees. An angle between an absorption axis of the first polarizer sheet and a major axis of a liquid crystal molecule adjacent thereto ranges from 80 degrees to 85 degrees, and an angle between an absorption axis of the second polarizer sheet and a liquid crystal molecule adjacent thereto ranges from 50 degrees to 55 degrees.
