Abstract

It is possible to provide a liquid crystal panel, a liquid crystal television, and a liquid crystal display device capable of reducing the light leak and slight coloring in black display of a liquid crystal display device, increasing the contrast ratio in the oblique direction, and reducing the color shift amount in the oblique direction. A liquid crystal panel includes a liquid crystal cell having a liquid crystal layer containing nematic liquid crystal homogeneously orientated when no field is present, a first polarizer arranged at one side of the liquid crystal cell, a first layered optical element arranged between the liquid crystal cell and the first polarizer, a second polarizer arranged at the other side of the liquid crystal cell, and a second layered optical element arranged between the liquid crystal cell and the second polarizer.

Description

technical field

[0001] The present invention relates to a liquid crystal panel, a liquid crystal television, and a liquid crystal display device each having improved display properties by incorporating a laminated optical element. Background technique

[0002] Liquid crystal display devices attract attention because of their characteristics such as thinness, light weight, and low power consumption, and are widely used in: portable equipment such as mobile phones and watches; office automation (OA) equipment such as personal computer monitors and laptop personal computers; and home appliances such as video cameras and LCD TVs. Due to technological innovation, the defects that the display characteristics of the liquid crystal display device change with the viewing angle of the screen and the liquid crystal display device cannot work at high temperature and extremely low temperature have been overcome, so that the liquid crystal display device is widely used. However, a wide r...
