Problems solved by technology

As a result, a part of the polarized light component passes through the cross-Nicol-type polarizing plates arranged on the exit surface side and acts in a direction to brighten the black level on the screen, thereby lowering the contrast ratio.
Moreover, when the liquid crystal molecules in the liquid crystal layer are aligned horizontally or in the middle, it is unavoidable to reduce the quality of the displayed image due to the difference in birefringence caused by the angle of light incident on the liquid crystal layer.

Embodiment Construction

[0032] The phase difference compensation element of the present invention is composed of, for example, figure 1 The sputtering device shown is manufactured. The sputtering device, although its structure is basically Figure 7 The conventional device shown is the same, but the drum body 6 supporting the substrate 7 is provided with a mechanism for rotating the substrate 7 around its normal line. In addition, a freely rotatable substrate holder 24 is provided on the outer peripheral surface of the drum body 6, and the substrate holder 24 holds five substrates 7a-7e, and these substrates 7a-7e can surround it as the substrate holder 24 rotates 90° The normal is rotated by 90°. In addition, the 90° rotation direction may be either clockwise or counterclockwise.

[0033] The other components of the sputtering device and Figure 7 The conventional device shown is the same, and the target material 9 uses Nb with high refractive index. 2 O 5 The film-forming material Nb, the target mater...

Abstract

This invention provides a phase difference compensating component and manufacturing method thereof, wherein the phase difference compensating effect generated by a phase difference compensation layer with multi-layer structure where films with different reflection ratio are alternately laminated is improved; substrates (7a to 7e) are kept by a rotary drum body (6); the phase difference compensating layer is enabled to spattered to form film by utilizing the rotary drum body (6), at the same time utilizing a spattering particles from a target materials (9, 10). After a first unit equal to ahalf of the phase difference compensation layer is formed a film, a substrate bracket (24) is rotated so as to enable each substrate (7a to 7e) to rotate 90 degrees surrounding a normal. Then a second layer for composing the rest half of the phase difference compensating layer is formed a film by using the same mode.

Description

Technical field [0001] The present invention relates to a phase difference compensation element used in combination with a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] Liquid crystal display panels are mostly used in direct-view display devices of television receivers or various devices, and can also be used as image display devices of liquid crystal projectors. A liquid crystal display panel has a plurality of liquid crystal cells arranged in a predetermined pattern corresponding to the pixel arrangement. Depending on the operation mode of the liquid crystal molecules enclosed in the liquid crystal cell, the following types are known, namely TN (Twisted Nematic) type, VAN ( Vertical Alignment Nematic) type, IPS (In-Plane Switching) type, OCB (Optically Compensatory Bend) type, etc. [0003] In the liquid crystal display panel used in the liquid crystal projector, in order to improve the contrast of the image on the screen, a type ...
