  • Patent number: 11004390
    Abstract: A display panel including pixels disposed on a substrate, where each of the pixels includes a light emitting element, and a capacitor. The capacitor of a first one of the pixels is partially overlapped, in a vertical direction, by respective pixel areas of two of the pixels. The anode of the capacitor of the first one of the pixels may be disposed closer to the substrate than a cathode of the capacitor, thereby reducing a parasitic capacitance between the capacitor and an anode of the light emitting element of one of the two pixels overlapping the capacitor.

  • Patent number: 10998382
    Abstract: A self-light emitting display unit capable of improving manufacturing yield is provided. Sizes of color pixel circuits corresponding to pixels for R, G, and B are respectively set unevenly within a pixel circuit according to a magnitude ratio of drive currents which allow color self-light emitting elements in the pixel to emit with a same light emission luminance. Thereby, the pattern densities of color pixel circuits respectively corresponding to the pixels for R, G, and B become even to each other, and the pattern defect rate as the whole pixel circuit is decreased.

  • Patent number: 10960426
    Abstract: A slit nozzle is moved by a nozzle lifting/lowering mechanism and a nozzle sliding mechanism relative to substrates held in a substantially horizontal attitude by spin chucks. A development liquid is discharged on each substrate from a discharge port of the slit nozzle such that development processing for the substrate is performed. After the development liquid is discharged, the slit nozzle is moved to a waiting position excluding positions over the substrates held by the spin chucks. In waiting pods provided at the waiting positions, cleaning processing for the slit nozzle is performed by a cleaning liquid with gas bubbles mixed therein.

  • Patent number: 10621917
    Abstract: A display device of the disclosure includes a plurality of pixels and a driver. The driver unit makes scanning of pixels that belong to a plurality of pixel lines out of the plurality of pixels, in units of pixel line groups each of which is constituted by a predetermined number of the pixel lines, in a scanning order indicated by scanning ordinal numbers associated with the respective pixel line groups, to perform a write drive that includes writing a pixel voltage to each pixel. The scanning ordinal numbers are set to allow a sum of the scanning ordinal numbers of any two adjacent pixel line groups to approximate to a predetermined value.
