  • Substrate separation apparatus for stacked body
    Patent number: 9805953
    Abstract: A wedge-shaped jig (6) is inserted into a gap between a first substrate (21) and a second substrate (22) at a corner (221) of the second substrate (22) and separation of the attached first substrate (21) and second substrate (22) starts to proceed; then, a second suction pad (53) of a second suction portion (51), which is the closest to the corner (221), moves upward. Then, first suction pads (43) of first suction portions (41a), (41b), and (41c) sequentially move upward such that one side of the second substrate (22) separates from the stacked body. Although the second substrate (22) warps as the separation of the second substrate (22) proceeds, each of the plurality of first suction pads (43) elastically deforms. Therefore, the first suction pads (43) can be prevented from being detached from the second substrate (22), and the substrate (22) can be securely separated from the stacked body.

  • Liquid crystal display device
    Patent number: 9798204
    Abstract: Disclination of an active matrix liquid crystal display device is reduced. Portions of pixel electrodes are formed so as to mutually overlap with a convex portion. If the height of the convex portion is too tall, the amount of light leakage increases due to liquid crystals orienting diagonally with respect to a substrate surface. (See FIG. 1C.) If the height of the convex portion is low, the disclination reduction effect is low. The optimal convex portion height is thus determined.
