  • Patent number: 11919371
    Abstract: A window stabilization mechanism includes a rail provided on a first cabin frame provided on one side of a window, and has a first end and a second end opposite to the first end in the lengthwise direction of the rail. A sliding member is provided on a windowpane and is configured to slide on the rail. The sliding member is located at a first end when the window is opened and at a second end when the window is closed. A lock mechanism is configured to lock the windowpane to the first cabin frame when the window is closed. A window support member is configured to abut on the windowpane when the window is closed, and to press the windowpane in an oblique direction from the windowpane toward the rail and from the second end toward the first end when the windowpane is locked by a lock mechanism.

  • Patent number: 10795229
    Abstract: An element substrate of an electro-optical device includes, in a peripheral area surrounding a pixel area, a metal wiring provided at one surface side of a first substrate that is a substrate body, and a plurality of second light-shielding layers overlapping with the metal wiring between the first substrate and the metal wiring. A second light-shielding interlayer area overlapping with the metal wiring is present between the plurality of second light-shielding layers. A third light-shielding layer is formed in a manner overlapping in a plan view with the second light-shielding interlayer area between the first substrate and the metal wiring. Surfaces of the second light-shielding layer and the third light-shielding layer at the first substrate side have lower reflectance than a surface of the metal wiring at the first substrate side.

  • Patent number: 8717275
    Abstract: A circuit includes a first logic circuit section that outputs a signal that could be in an active voltage level depending on a transfer-signal input from a shift register throughout a display period and outputs a signal whose voltage is constant at the active voltage level throughout an off sequence period; an enable signal output section that outputs an enable signal that is pulsed during the display period; and a second logic circuit section that outputs a signal corresponding to a logical product of the output signal of the first logic circuit section and the enable signal. The enable signal output section keeps the voltage of the enable signal constant at the active voltage level throughout the off sequence period.

  • Patent number: 8643014
    Abstract: An electro-optical device is provided with a data line which are provided in a pixel region, a pixel electrode formed from a transparent conductive material which is upper layer than the data line, a storage capacitance electrode which is provided in a layer between the pixel electrode and the data line so as to face the pixel electrode via a capacitance insulation film, an additional capacitance which has a first capacitance electrode and a second capacitance electrode which is formed in the same layer as the pixel electrode and the storage capacitance electrode, respectively. The second capacitance electrode is electrically connected to the data line.

  • Patent number: 8269710
    Abstract: An electro-optical device includes red, green, and blue sub pixels and red, green, and blue data lines connected to the corresponding sub pixels. Red, green, and blue sampling switches are provided in a peripheral region and are electrically connected to data lines of the corresponding color. The green sampling switch is located at a position that is closer to the pixel region than are the red or blue sampling switches.

  • Patent number: 8207925
    Abstract: An electro-optical device includes three data lines intersecting a scanning line. Three sampling circuits are aligned in a different direction than the direction in which three (R, G, B) sub pixel units are aligned. An image signal line of one sampling circuit extends across the gate electrode of a transistor in another one of the sampling circuits.
