  • Publication number: 20160018708
    Abstract: A display device is provided that inhibits color mixture between adjacent subpixels and allows for obtaining a high-quality image. The display device includes a display area on which a light-blocking metal layer, a black matrix, and a plurality of subpixels are arranged, wherein the plurality of subpixels are arranged adjacent to one another via a black matrix as seen vertically from above, the black matrix and the light-blocking metal layer are arranged to overlap each other as seen vertically from above, and the light-blocking metal layer 130 is arranged on the bank of an organic flattened film.

  • Publication number: 20150286080
    Abstract: Recently, with an increasing demand for narrowing a frame, the seal line width is inclined to get finer, which deteriorates the seal adhesive strength. One or a plurality of grooves are formed in a resin layer that is a foundation of a seal area. A direction of forming a groove (lateral surface) is preferably in a vertical direction to the external stress. In a seal straight portion, a groove is preferably formed not only in a parallel direction to the seal but also in the vertical direction. In a seal corner portion, a groove is preferably formed in a shape curved convexly toward a direction of a display area (active area).

  • Publication number: 20150261046
    Abstract: In the case of a pixel including four and more sub pixels, the area of one pixel is larger than that in the case of a pixel including three sub pixels; therefore, high definition becomes difficult. When a central display area has a structure of four and more sub pixels, in a display device, the pixel structure in a peripheral display area for use in creating a virtual image is reduced to three sub pixels, to allocate the vacant space for high density assignment. Only the pixel density in the vicinity of a frame of a lens portion is compressed, in order to apparently resolve the discord with the image of a non-lens portion. The pixel side in the peripheral display area may be even or gradually narrowed.

  • Patent number: 8686989
    Abstract: In one embodiment, the liquid crystal shutter is equipped with a first liquid crystal panel in the OCB mode to control the transmissivity of the light entering into left eye and a second liquid crystal panel in the OCB mode to control the transmissivity of the light entering into right eye, and a drive portion to control the transmissivity. The drive portion applies a normal voltage of a normal drive in a pulse shape and a retention voltage having a pulse shape with lower frequency than the normal voltage or lower voltage than normal voltage to the first liquid crystal panel and the second liquid crystal panel. The drive portion switches between the normal drive and the retention drive while maintaining bend alignment state.
