Patent number: 7133109Abstract: A liquid crystal display apparatus includes first and second substrates, a liquid crystal layer, a sealing member, and first and second spacers. The first substrate includes a first display part having a pixel electrode formed thereon. The second substrate includes a second display part having a common electrode. The liquid crystal layer is interposed between the first and second substrates. The seal line includes a liquid crystal inlet. The first spacer is disposed between the first and second display parts. The second spacer is disposed near the liquid crystal inlet. The second and third spacers prevent the cell gap of the liquid crystal inlet from being narrowed, so that a liquid crystal material may be injected easily completely. Thus, the liquid crystal material is completely filled to enhance the display quality.Type: GrantFiled: March 22, 2004Date of Patent: November 7, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Yun Jang, Hye-Rhee Han, Kye-Hun Lee, Young-Goo Song

Publication number: 20060176435Abstract: A tetragonal ring shape aperture is formed in the common electrode on one substrate and a cross shape aperture is formed at the position corresponding to the center of the tetragonal ring shape aperture in the pixel electrode on the other substrate. A liquid crystal layer between two electrodes are divided to four domains where the directors of the liquid crystal layer have different angles when a voltage is applied to the electrodes. The directors in adjacent domains make a right angle. The tetragonal ring shape aperture is broken at midpoint of each side of the tetragon, and the width of the aperture decreases as goes from the bent point to the edge. Wide viewing angle is obtained by four domains where the directors of the liquid crystal layer indicate different directions, disclination is removed and luminance increases.Type: ApplicationFiled: April 6, 2006Publication date: August 10, 2006Inventors: Jang-Kun Song, Kyeong-Hyeon Kim, Kye-Hun Lee, Hea-Ri Lee

Patent number: 7061562Abstract: In a vertically aligned mode LCD, a gate line and a storage line are formed on a substrate in parallel, and a storage electrode and a cover pattern are formed as branches of the storage line. The storage electrode is overlapped with an aperture of a common electrode formed on an upper substrate. The cover pattern is located between a pixel electrode and a data line to prevent a light leakage. Accordingly, an alignment error margin of the upper substrate and the lower substrate is increased, an aperture ratio is enhanced, and repairing the high pixel defect is possible. Further, the light leakage caused by a voltage of the data line is prevented.Type: GrantFiled: May 7, 2003Date of Patent: June 13, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Kyeong-Hyeon Kim, Kye-Hun Lee, Seung-Beom Park, Jang-Kun Song

Publication number: 20030202144Abstract: Saw-shaped protrusions, which are parallel to each other, are formed on the common electrode and the pixel electrode in two substrates. Protrusions in two substrates are arranged alternately and the bent portions of the saw-shaped protrusions are placed on the line transverse passing through the center of a pixel. Branches extend from the convex point of one saw-shaped protrusion toward the apex to the other saw-shaped protrusion, and another branch extend from the point where the protrusion meets the boundary of the pixel electrode toward the point where the boundary of the pixel electrode and the saw-shaped protrusion make an acute angle.
