Patent number: 7894025Abstract: An LCD including a color filter substrate, an array substrate, and a liquid crystal layer therebetween is provided. This color filter substrate has a plurality of color filters with overlap regions acting as a black matrix. Subsequently, patterned regions are defined in part of the overlap regions. After formation of a planarization layer and a conductive layer, spacers are formed in the patterned regions. The spacers may not shield the transparent region of the color filters, thereby enhancing the aperture ratio of the color filter substrate. Additionally, the thickness of the planarization layer in the patterned regions is not influenced by the overlap of the color filters, such that the spacers thereon have a uniform height. Furthermore, the at least one spacer of the color filter substrate and at least one data line of the array substrate are overlapped.Type: GrantFiled: March 15, 2010Date of Patent: February 22, 2011Assignee: Au Optronics Corp.Inventors: Ching-Sheng Cheng, Chih-Jen Hu
