Abstract: According to an aspect, a display device includes: a substrate; a plurality of pixels provided on the substrate; and a first light emitting element and a second light emitting element that are included in each of the pixels. A light emitting layer of the first light emitting element includes gallium nitride to which europium is added, and a light emitting layer of the second light emitting element includes a multi-quantum well structure in which indium gallium nitride and gallium nitride are layered.

Abstract: A liquid crystal display device has a pair of wall electrodes facing each other, which is disposed on pixels on a first substrate, functions as one of pixel electrodes and a common electrode, and takes a posture of standing on the first substrate. Also, the liquid crystal display device has a center electrode that is disposed between the pair of wall electrodes, functions as the other of the pixel electrodes and the common electrode, has a convexity lower in height than the pair of wall electrodes, and makes a width in a direction along which the pair of wall electrodes faces each other gradually smaller toward the second substrate. According to this liquid crystal display device, since a vertical electric field can be prevented from being developed on an upper side of the center electrode, a transmittance of light can be improved.

Abstract translation: 液晶显示装置具有彼此面对的一对壁电极，其设置在第一基板上的像素上，用作像素电极和公共电极之一，并且在第一基板上具有站立姿态。 此外，液晶显示装置具有设置在一对壁电极之间的中心电极，作为像素电极和公共电极中的另一个具有比一对壁电极高的凸度，并且使 一对壁电极彼此面对的方向上的宽度朝向第二基板逐渐变小。 根据该液晶显示装置，由于可以防止在中心电极的上侧显示垂直电场，所以可以提高光的透射率。
