Problems solved by technology

However, this method of setting the platform 116 reduces the aperture ratio instead, and as shown in FIG. 1B , several positions where spacers 123 are often designed also cause the problem of wasting the aperture ratio.
[0008] In order to solve the above-mentioned problems of reduced contrast and aperture ratio, in the current liquid crystal display manufacturing process, attempts are often made to adjust the positions of alignment bumps 122, spacers 123, or contact holes 115.

Embodiment Construction

[0028] In FIG. 1C , since the spacer 123 must just abut against both sides of the opening of the contact hole 115 , the panel spacing can be maintained stably. In this way, slight errors in the manufacturing process, such as: the width of the spacer, the opening width of the contact hole, and the alignment error between the array substrate and the color filter during assembly, etc., are very likely to cause errors in the cell gap of the panel and lead to a poor yield loss situation.

[0029] In view of this, in order to improve the problems of poor contrast and reduced aperture ratio caused by conventional liquid crystal display technology, the present invention proposes a new design, which can not only increase the aperture ratio of liquid crystal display, but also further Improve its image contrast.

[0030] The present invention is hereby described in detail in conjunction with the drawings, and the preferred embodiments and related application descriptions thereof are lis...

Abstract

A liquid crystal face plate is prepared for forming the first base plate with a numbers of sub-pixels by the first substrate, switch element array set on the first substrate, UHA on switch element array, contact hole and a reflection electrode set on UHA and electric-connected to on switch element of switch element array through said contact hole; arranging a packing component between the first and the second base plates and filling said packing component full of contact hole then setting a liquid crystal layer between the first and the second base plates.

Description

【Technical field】 [0001] The present invention relates to a display, in particular to a reflective or transflective liquid crystal display with high aperture ratio and high contrast. 【Background technique】 [0002] With the advancement of science and technology, liquid crystal displays with many advantages such as power saving, no radiation, small size, low power consumption, right-angle plane, high resolution, and stable image quality have become the traditional image tube (referred to as CRT) has brought a great impact, especially today's various information products such as mobile phones, notebook computers, digital cameras, PDAs, LCD screens and other products are becoming more and more popular, which also greatly increases the demand for liquid crystal displays (LCDs) . [0003] Liquid crystal displays can be divided into three types according to their light source mechanisms: transmissive, reflective, and transflective. Among them, the transmissive liquid crystal dis...
