Embodiment Construction

[0027] The liquid crystal-on-silicon chip in the prior art is likely to be poorly matched with the subsequent prepared liquid crystal layer. The shape of the pixel electrode 110 in the liquid crystal-on-silicon chip known to the inventor is generally square, such as figure 1 shown. The inventors have found through research that semiconductor processes such as wet etching will be used in the preparation of the pixel electrode 110, and these semiconductor processes will cause corrosion pits to be formed on the edge of the pixel electrode 110 (such as figure 2 Indicated by the dotted line area in the middle), the existence of corrosion pits will lead to poor matching of the subsequent liquid crystal layer.

[0028] The inventors have further studied and found that if the pixel electrode has the same area and the side length of the pixel electrode can be reduced, the probability of corrosion pits will be correspondingly reduced, thereby reducing the chance of poor matching of the...

Abstract

The invention discloses a silicon-based liquid crystal chip. The silicon-based liquid crystal chip comprises a substrate and a plurality of pixel electrodes which are arranged on the substrate in an array form, wherein the transverse section of each pixel electrode is in an n-edge shape or a circular shape, wherein n is greater than or equal to 5, the perimeter of each pixel electrode is C1, the perimeter of a square with the same area with each pixel electrode is C2, and C1 is smaller than C2. The invention also provides a display device comprising the silicon-based liquid crystal chip. The silicon-based liquid crystal chip and the display device can effectively avoid the unfavorable matching problem of the silicon-based liquid crystal chip and a liquid crystal layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a silicon-based liquid crystal chip and a display device. Background technique [0002] In recent years, electronic display technology has been rapidly developed, and the conventional cathode ray tube display has been gradually replaced by new display devices such as liquid crystal displays (LCDs). Many computer terminals and small portable digital products rely on liquid crystal displays to output video, text and other content. Unfortunately, the yield of liquid crystal panels is relatively low, especially the production of large-sized liquid crystal panels is still relatively difficult, and the production cost is relatively high. [0003] In addition to liquid crystal displays, other forms of display technologies have also been greatly developed. For example, liquid crystal on silicon (LCOS, Liquid Cristalon Silicon) display devices have been extensively researched due to adv...
