Patent number: 6573954Abstract: A liquid crystal display device which includes an active element substrate in which a pixel electrode on an upper layer is connected to active element TFT beneath an interlayer insulation film through a contact hole provided on the interlayer insulation film beneath the upper layer. The contact hole has an approximately oval shape, and a major axis portion extending, roughly along a major axis of the contact hole, from the contact hole in the pixel electrode to nearby pixel electrode edges is located in a light-shielded area of the active element substrate. This prevents the occurrence of a defective pixel area, even a crack is generated in the pixel electrode, without reducing the aperture ratio.Type: GrantFiled: December 22, 1999Date of Patent: June 3, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Hirose, Nobuyuki Tsuboi, Tatsuya Wakimoto
