Abstract: According to one embodiment, a display device includes a switching liquid crystal unit, a display, and a controller. The switching liquid crystal unit includes optical elements switching an aperture pattern including an aperture portion and a light-shielding portion. The display overlaps the switching liquid crystal unit and displays parallax images including right and left eye images. The controller acquires positional information relating to a position of a viewer, and controls a position of the aperture pattern. The controller switches the aperture pattern from a first aperture pattern to a second aperture pattern so that a right eye always views the right eye image and a left eye always views the left eye image, and starts the switching before the viewer moves to an optimal switching position where a luminance viewed from the first aperture pattern is substantially equal to a luminance viewed from the second aperture patterns.

Abstract: A display device includes a signal processing unit that receives input signals, and calculates output signals to a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The signal processing unit calculates a frequency of pixels belonging to each of a plurality of partitions using a light quantity of a surface light source. The signal processing unit calculates an index value for each of the partitions by at least multiplying the cumulative frequency being obtained by sequentially adding the frequency of pixels from a partition having the maximum light quantity among the partitions, and the number of partitions representing a position of a partition to which the cumulative frequency belongs counted from the partition having the maximum light quantity. The signal processing unit controls luminance of the surface light source based on a partition in which the index value exceeds a threshold.
