    • The present invention has an object of providing a liquid crystal display device having a high transmittance or a high viewing angle characteristic. A liquid crystal display device according to the present invention includes a pixel electrode (30) including a peripheral portion (36), an island portion (32) and a plurality of branch portions (34). The plurality of branch portions (34) are formed of a plurality of first through fourth branch portions (34A through 34D) respectively extending in first through fourth directions. By these branch portions, first through fourth regions (35A through 35D) in which liquid crystal molecules are aligned in different directions from each other at the time of voltage application are formed. The island portion (32) is surrounded by the first through fourth regions (35A through 35D), and is connected to the peripheral portion (36) by a connection portion (38) but not by any of the plurality of branch portions (34) or connected to the peripheral portion (36) by one of the first through fourth branch portions (34A through 34D).
    • 本发明的目的是提供具有高透射率或高视角特性的液晶显示装置。 根据本发明的液晶显示装置包括具有周边部分(36),岛部(32)和多个分支部分(34)的像素电极(30)。 多个分支部分(34)由分别沿第一至第四方向延伸的多个第一至第四分支部分(34A至34D)形成。 通过这些分支部分,形成在施加电压时将液晶分子彼此不同方向排列的第一至第四区域(35A至35D)。 岛部32由第一至第四区域35A〜35D包围,并且通过连接部38而不由多个分支部34中的任一个与周边部36连接, 或者通过第一至第四分支部分(34A至34D)之一连接到周边部分(36)。

    • Disclosed is an MVA type liquid crystal display device (LCD 100A) forming four domains in which liquid crystal molecules fall in different directions that are about 90° apart. The MVA type liquid crystal display device includes a plurality of pixels arranged in a matrix of rows and columns, which pixels are horizontally long pixels having longer sides extending in the row direction. Each pixel includes two first electrodes (21a and 21b) arranged side by side along the row direction. Preferably, at least one of the two first electrodes (21a and 21b) has a first corner section including a first edge that is parallel to the row direction and a second edge that is parallel to the column direction, and the first substrate further includes an electrode layer (16c) overlapping at least a portion of the first edge or the second edge of the first corner section. According to the present invention, display quality deterioration caused by disturbed alignment of liquid crystal molecules occurring near the edges of the pixel electrodes can be suppressed.
    • 公开了一种MVA型液晶显示装置(LCD 100A),其形成四个畴,其中液晶分子沿相差约90°的不同方向落下。 MVA型液晶显示装置包括排列成行和列的矩阵的多个像素,这些像素是沿着行方向延伸的长边的水平长的像素。 每个像素包括沿着行方向并排布置的两个第一电极(21a和21b)。 优选地,两个第一电极(21a和21b)中的至少一个具有包括平行于行方向的第一边缘和平行于列方向的第二边缘的第一拐角部分,并且第一基板还包括 电极层(16c)与第一角部的第一边缘或第二边缘的至少一部分重叠。 根据本发明,可以抑制由像素电极的边缘附近发生的液晶分子的被扰乱的取向引起的显示质量恶化。
