Abstract: According to one embodiment, an electronic device includes a display panel, a first sensor, a memory unit, and a controller. During a first period, the controller generates first image data, stores the first image data in the memory unit, and displays a first character in a display area of the display panel. During a second period, the controller generates second image data, and records the second image data in the memory unit. During a third period, the controller displays a second character instead of the first character, in the display area. The second character is a character obtained by flipping the first character.

Abstract: A display device includes an array substrate, a counter substrate, and a liquid crystal layer between the array substrate and the counter substrate. The array substrate includes signal lines, scan lines, a grid-shaped organic insulating layer covering over the scan lines and the signal lines, pixel electrodes, and a first orientation film covering the pixel electrodes. A portion of each pixel electrode is provided above a slant surface of the organic insulating layer and overlaps the slant surface. The counter substrate includes a common electrode overlapping the pixel electrodes, an insulating protective film covering the common electrode, and a second orientation film covering the protective film and the common electrode. A region overlapping an opening surrounded by the scan lines and the signal lines has a non-overlapping region of the protective film where the common electrode and the second orientation film are directly stacked without interposing the protective film therebetween.
