    Abstract: Disclosed herein is a display device including a reflection type image display portion having a sheet-like anisotropic scattering member. In an area, in an in-plane direction, of the anisotropic scattering member, a low-refractive index area and a high-refractive index area are disposed in a mixture style. The anisotropic scattering member is disposed in such a way that a light is scattered when an outside light is made incident from a surface side on which a degree of a change in a refractive index in a vicinity of a boundary between the low-refractive index area and the high-refractive index area is relatively large, and is emitted from a surface side on which the degree of the change in the refractive index in the vicinity of the boundary between the low-refractive index area and the high-refractive index area is relatively small.

    Abstract: According to an aspect, a display device includes: an image display panel; a color conversion device including a signal processing unit and a signal output unit; a planar light-source device; and a light-source-device control unit. The signal processing unit includes a color conversion circuit that converts an input signal in a reference color area into a converted input signal generated in a definition color area where a chromaticity point of at least one of a first color, a second color, and a third color is inside of a reference color area, and a four-color generation circuit that generates an output signal and a light-source-device control signal from the converted input signal. The signal output unit outputs the drive signal to each sub-pixel based on the output signal. The light-source-device control unit outputs a drive voltage for emitting white light on the planar light-source device based on the light-source-device control signal.

    Abstract: According to an aspect, a display device includes: sub-pixels arranged in row and column directions and each including a memory block including memories to store therein sub-pixel data; memory selection line groups corresponding to rows and each including memory selection lines electrically coupled to the memory blocks in the respective sub-pixels that belong to the corresponding row; and a memory selection circuit configured to concurrently output a memory selection signal to the memory selection line groups. Each sub-pixel displays an image based on the sub-pixel data stored in one of the memories in accordance with the memory selection line supplied with the memory selection signal. The number of times that the set value is changed is less than the number of times that images are switched from one to another based on the memory selection signal output from the memory selection circuit.

In an area, in an in-plane direction, of the anisotropic scattering member, a low-refractive index area and a high-refractive index area are disposed in a mixture style. The anisotropic scattering member is disposed so that a light is scattered when an outside light is made incident from a surface side on which a degree of a change in a refractive index in a vicinity of a boundary between the low-refractive index area and the high-refractive index area is relatively large, and is emitted from a surface side on which the degree of the change in the refractive index in the vicinity of the boundary between the low-refractive index area and the high-refractive index area is relatively small.
