Abstract: A liquid crystal display device that performs phase inversion drive in which a phase of a polarity of a data voltage is inverted in predetermined timing while performing frame inversion drive in which a positive-polarity data voltage and a negative-polarity data voltage are alternately output to a data line in each one or plurality of frames. In a first frame immediately after the phase is inverted, the source driver outputs a second data voltage to the data line in initial first periods of a horizontal scanning period, the second data voltage being closer to the common voltage than a first data voltage corresponding to input image data, and outputs the first data voltage to the data line in a second period after the first period in the horizontal scanning period.

Abstract: A display device includes a display portion comprising pixels including a first pixel and a second pixel, a source driver for applying a pixel voltage to pixels through signal lines, and a control portion for controlling the source driver. The first and second pixels each include a first sub-pixel and a second sub-pixel. The first sub-pixel includes a light exit portion and a color filter for a first hue. The second sub-pixel includes a light exit portion and a color filter for a second hue. An area of the light exit portion of the first sub-pixel of the first pixel is smaller than that of the first sub-pixel of the second pixel. The control portion converts the video signal for the first sub-pixel into a brighter one. The source driver applies the pixel voltage to the first sub-pixel of the first pixel based on the video signal after conversion.

Abstract: A display device includes a divided display region that includes pixels and gate drivers each configured to scan gate lines included in the divided display region. The display device also includes source drivers each configured to output, for each of groups of data lines, a video signal based on a grayscale signal in order from a corresponding gate driver side based on each delay amount set in advance and a register unit configured to store the each delay amount. The register unit stores the each delay amount so that, when at least one gate driver scans in a first order from an edge of the divided display region toward a center, the video signal corresponding to the pixels positioned on a centermost side of the display region is output to the pixels, in a period including a part of a vertical flyback period of after one frame period has finished.

Abstract: The present implementation discloses a display device including first pixels each of which has a first emission region for emitting image light for displaying an image; and second pixels each of which has a second emission region for emitting the image light. Each of the first and second pixels has optical transmission sections which emit different image lights in hue from each other. The optical transmission sections forms a first transmission region for emitting an image light of a hue which has a predetermined contribution ratio to luminance, and a second transmission region for emitting an image light of a hue with a contribution ratio higher than that of the first transmission region. The first emission region is narrower than the second emission region by a difference in area size between the first transmission regions in the first and second emission regions.
