  • Publication number: 20180301086
    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: 10014355
    Abstract: The display device including a pixel circuit has a first line, a transistor, a light emitting element, and a second line. The transistor is located between the second line and an electrode of the light emitting element. Either the first line or the second line is wired in a region that overlaps a light emitting region of the light emitting element in a lamination direction of layers. The second line intersects the first line outside of the light emitting region and overlaps a non-light emitting region of the light emitting element.

  • Publication number: 20180097054
    Abstract: A display device including a pixel array unit having a matrix of pixels each configured such that an anode electrode of an organic electroluminescent element is connected to a source electrode of a drive transistor, a gate electrode of the drive transistor is connected to a source or drain electrode of a writing transistor, and a storage capacitor is connected between the gate and source electrodes of the drive transistor, scanning lines and power supply lines for individual pixel rows, and signal lines for individual pixel columns. A video signal reference potential is supplied to the signal lines for a period during which a scanning signal is supplied to the scanning lines during driving of pixels in a preceding row. During threshold correction for the drive transistor in a current pixel, the video signal reference potential and a potential of the cathode electrode of the organic electroluminescent element are equal.
