Patent number: 9030631Abstract: The present disclosure provides a liquid crystal displaying panel, which includes a first substrate having a displaying area and a sealant-coating area surrounding the displaying area and a light-blocking layer arranged between the displaying area and the sealant-coating area. The light-blocking layer can absorb and block ultraviolet light to prevent the ultraviolet light from affecting the liquid crystal layer. Additionally, the light-blocking layer and the pixel electrode layer are formed in the same process, that is, the light-blocking layer is simultaneously formed when the pixel electrode layer is formed. A thickness of the light-blocking layer is equal to that of the pixel electrode layer. Since the thickness of the light-blocking layer is equal to that of the pixel electrode layer, the pixel electrode layer and the light-blocking layer can be formed in the same process, which simplifies the manufacturing process of the light-blocking layer and the needed equipment.Type: GrantFiled: December 14, 2012Date of Patent: May 12, 2015Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventor: Liang Xu

Patent number: 8994908Abstract: In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.Type: GrantFiled: March 28, 2013Date of Patent: March 31, 2015Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Chikae Matsui, Hidehiro Sonoda, Noboru Kunimatsu
