Abstract: a display device includes liquid crystal panels, and displays an image, based on emission light from each of the liquid crystal panels. a display control circuit of the display device supplies image data of respective colors r, g, and b to the corresponding liquid crystal panels. a panel pixel having the lowest transmittance of three panel pixels corresponding to white-side pixels at domain boundaries is regarded as a reference panel pixel. the display control circuit reduces a gray scale level of pixel data supplied to two panel pixels other than the reference panel pixel of the three panel pixels. with this, coloring of the white-side pixels can be suppressed.

Abstract: when a size of a document is not specified, a control unit of an image reading device identifies, for image data generated as a reading result by a reading unit, a region of the document by detecting an edge of the document. when the size of the document is specified, the control unit searches the image data, at a position within a first range including a position away from an origin by a first distance, for a downstream end of the document from a downstream end of the image data toward upstream in a transport direction, and based on a position of the downstream end of the document identified by the searching, identifies as a region of the document a region corresponding to the size of the document specified.
