Liquid crystal display device

Abstract

Abstract PURPOSE:To obtain a liquid crystal display device characterized by high display contrast and high brightness of displayed colors and a wide visual angle by using a light angle limiting member. CONSTITUTION:A liquid crystal cell 50 is formed by a lower substrate 4, a driving electrode for a liquid crystal layer and an orientation layer 5 and polarizing plates 3, 7 are formed on the front and back of the cell 50. The liquid crystal layer 5 is formed by TN liquid crystal and GH liquid crystal. The driving electrode and the orientation layer are formed on one surface of an upper substrate 60 to be used also as a total direction diffusing plate, a total direction diffusing surface 10 is formed on the other surface and the thickness of the upper substrate is preferably about the width of a display picture element. The polarizing axes of the polarizing plates and the orientation of the orientation layer are combined so that a prior visual field is turned to the shown arrow 9 direction. To keep the sharpness of the screen, it is necessary to set up the liquid crystal layer 5 close to the diffusion surface 10 as near as possible.
