Publication number: 20140111716Abstract: A liquid crystal display panel having pixel regions includes a light shielding layer having opening regions corresponding to the pixel regions, first pixel electrodes and second pixel electrodes. Each first pixel electrode includes strip first pixel electrode patterns. Each second pixel electrode includes strip second pixel electrode patterns. Each opening region includes sub regions. Each of the strip first pixel electrode patterns and its neighboring strip second pixel electrode pattern in each of the sub regions are separated by an electrode spacing. Electrode spacings in different sub regions are different. An area of all the sub regions with the electrode spacings less than or equal to 12 micrometers accounts for less than or equal to 35% area of each opening region. An area of the other sub regions with the electrode spacings greater than 12 micrometers accounts for more than or equal to 65% area of each opening region.Type: ApplicationFiled: March 1, 2013Publication date: April 24, 2014Applicant: AU OPTRONICS CORPORATIONInventors: Sau-Wen Tsao, Mei-Ju Lu, Cho-Yan Chen, Tien-Lun Ting

Publication number: 20140085583Abstract: A display panel includes a pixel structure that has first, second, and third sub-pixels. In the first sub-pixel, a first pixel electrode having first branches and a second pixel electrode having second branches are alternately arranged. Gap dB is defined between adjacent first and second branches. In the second sub-pixel, a third pixel electrode having third branches and a fourth pixel electrode having fourth branches are alternately arranged. Gap dG is defined between adjacent third and fourth branches. In the third sub-pixel, a fifth pixel electrode having fifth branches and a sixth pixel electrode having sixth branches are alternately arranged. Gap dR is defined between adjacent fifth and sixth branches. The gaps dB, dG, and dR at least include minimum gaps dBmin, dGmin, and dRmin and gaps dBn, dGn, and dRn, respectively. Here, dGn is equal to dRn, and (1/dBn)?[(1/dRn)*1.1].Type: ApplicationFiled: May 22, 2013Publication date: March 27, 2014Applicant: Au Optronics CorporationInventors: Mei-Ju Lu, Cho-Yan Chen, Kuan-Yu Chen, Sau-Wen Tsao, Yen-Ying Kung, Tien-Lun Ting
