However, it is known that the color filter layer has a depolarization effect, and the light depolarized by the color filter layer is scattered, and this phenomenon becomes one of the reasons for the increase of the transmitted light in a completely black state.

Abstract

A liquid-crystal display device comprising first and second polarizing elements, and a liquid-crystal cell disposed between the first and second polarizing elements, wherein the liquid-crystal cell comprises first and second substrates (provided that the first substrate is disposed closer to the first polarizing element, and the second substrate is disposed closer to the second polarizing element), a liquid-crystal layer disposed between the first and second substrates, a color filter layer disposed on an inner surface of the first substrate, and an in-cell polarizing layer disposed between the color filter layer and the liquid-crystal layer, the absorption axis of the first polarizing element and the absorption axis of the in-cell polarizing layer are parallel to each other, and the sum total of the absolute values of Re of all the layers disposed between the in-cell polarizing layer and the first polarizing element is equal to or less than 10 nm, and the sum total of the absolute values of Rth thereof is equal to or less than 15 nm.

Description

technical field [0001] The invention relates to a liquid crystal display device with a polarizing layer in a unit cell (cell) and a liquid crystal cell. Background technique [0002] In order to improve the contrast of a liquid crystal display device, various studies have been conducted on methods of reducing transmitted light in a front direction (ie, a direction normal to a display surface) in a completely black state. In a liquid crystal display device for color display, a color filter layer is provided for each pixel in a unit cell, and polarized light is incident on the color filter layer to display a color image. However, it is known that the color filter layer has a depolarization effect, and the light depolarized by the color filter layer is scattered, and this phenomenon becomes one of the reasons for the increase of the transmitted light in a completely black state. As a method for solving the increase in transmitted light in a completely black state due to the de...
