  • Patent number: 10180602
    Abstract: Red pixels (R), blue pixels (B) and green pixels (G) are formed in parallel. First columnar spacers 10 and second columnar spacers 20 are formed on a first substrate. The distance between the first substrate and a second substrate in a normal state is determined by the first columnar spacers 10. The diameter of a light blocking film corresponding to each first columnar spacer 10 is greater than the diameter of a light blocking film corresponding to each second columnar spacer 20. The first columnar spacer 10 is not formed at a boundary between a green pixel (G) and a red pixel (R) or a boundary between a green pixel (G) and a blue pixel (B). The second columnar spacer 20 is formed at a boundary between pixels irrespective of the pixel color. Thus, appropriate color balance can be attained with ease without having a drop in the luminance.

  • Patent number: 9789397
    Abstract: A game system executes a game that progresses in response to action commands issued on a plurality of electronic devices. When a first action command has been issued on a first electronic device, the system notifies a second electronic device, which is different from the first electronic device, of the issuance of the action command on the first electronic device. The system also sets a first time period until an action triggered by the first action command is reflected in the game, and after the elapse of the first time period from the time based on the first action command, reflects the action triggered by the first action command in the game executed by the second electronic device.

  • Patent number: 9627283
    Abstract: In a liquid crystal display device it is desirable to test in the state of TFT substrates, without reducing the number of TFT substrates to be obtained from one mother TFT substrate, and without increasing the overall size of the TFT substrates. Test terminals are formed on the outside of terminals for driving the liquid crystal display device. The test terminals of the specific TFT substrate are formed in another TFT substrate just below the specific TFT substrate. The area in which the test lines are formed is a space in which a sealing material is formed, between the display area and an end of the lower TFT substrate. Thus, the size of the TFT substrates is not actually increased. A test line area is not separately formed and not discarded, so that the number of TFT substrates to be obtained from one mother TFT substrate is not reduced.

  • Patent number: 9086588
    Abstract: A shielding metal of an adjacent liquid crystal panel separated from a mother substrate remains at an outer end part of a terminal portion of a liquid crystal display panel. The shielding metal has a two-layered structure including first shielding metals arranged at predetermined pitches and second shielding metals arranged at predetermined pitches. An insulating layer is provided between the first and the second shielding metals. This makes it possible to prevent short-circuit in wirings on a flexible wiring substrate even if the wirings on the flexible wiring substrate are brought into contact with the first or the second shielding metal.
