Abstract: A liquid crystal display device of one aspect of the present invention includes a liquid crystal display unit that includes a liquid crystal layer which exhibits vertical alignment and plural picture elements, and a control unit that controls a voltage which is supplied to the liquid crystal display unit. The control unit performs display by sequentially applying a first voltage that corresponds to a larger gradation number than an original gradation number and a second voltage that corresponds to zero gradation respectively in plural subframe periods that result from division of one frame period of an image signal in a case where the original gradation number of the input image signal is a low gradation number that is less than a prescribed threshold value, performs display by applying the second voltage in the one frame period in a case where the original gradation number is the zero gradation, and performs display by applying a third voltage that corresponds to the original gradation number in the one frame period in a case where the original gradation number is a high gradation number that is equivalent to or more than the threshold value.

Abstract: A light-emitting element includes an anode, a light-emitting layer, and a cathode disposed in this order. The light-emitting layer includes a plurality of quantum dots and an insulating material. An average value of a gap between a quantum dot in an end face portion of the light-emitting layer on the anode side and an end face of the light-emitting layer on the anode side is less than an average value of a gap between a quantum dot in an end face portion of the light-emitting layer on the cathode side and an end face of the light-emitting layer on the cathode side. Further, a display device includes a bank separating the light-emitting elements on a subpixel-by-subpixel basis. The light-emitting layer includes a main light-emitting portion including a light-emitting material, and an outer edge portion disposed at a position surrounding the main light-emitting portion in plan view of a substrate and including a deactivation material in which the light-emitting material is deactivated. The bank includes a forwardly tapered face on a side surface, and is in contact with the outer edge portion at the forwardly tapered face.
