摘要： According to an aspect, a display device includes a plurality of pixels. Each pixel includes two sub-pixels adjacent to each other in a first direction. Each sub-pixel has one of three colors allocated thereto. Two colors of the two sub-pixels included in the pixel are different. The two colors of the two sub-pixels and a positional relation between the two sub-pixels are the same in each of the pixels arrayed in a second direction. One color not allocated to the two sub-pixels included in a first pixel out of the three colors is allocated to at least one of the sub-pixels included in second pixels adjacent to the first pixel in the first direction. The sub-pixels having the same color allocated thereto are arranged along the first direction with one sub-pixel interposed therebetween, the one sub-pixel having another color allocated thereto.

摘要： According to an aspect, a display device includes an image display panel including: sub-pixel rows, in each of which sub-pixels for displaying different colors are periodically arrayed in a first direction, are regularly arranged in a second direction different from the first direction; signal lines in parallel to sub-pixel columns in which the sub-pixels are successively arranged in the second direction; and scan lines that sequentially select each sub-pixel row. Each of m (integer≥2) selector signals selects n (integer 1) pairs of the signal lines each supplied with two signals each having a mutually reverse polarity, within a period during which each sub-pixel row is selected by a corresponding scan line, and a sum of potential changes of the n pairs of the signal lines selected by each selector signal is substantially zero when each sub-pixel row is sequentially selected by the corresponding scan line.

The first and the second optical elements include a first and a second light exit surfaces, and the first and the second light exit surfaces are arranged to direct in different directions. The liquid crystal optical element has a second electrode group arranged adjacent to a first electrode group. The first electrode group has a first transparent electrode and a second transparent electrode. The second electrode group has a third transparent electrode and a fourth transparent electrode. A pitch at which the first transparent electrodes and the second transparent electrodes are alternately arranged is different from a pitch at which the third transparent electrodes and the fourth transparent electrodes are alternately arranged.
