Abstract: An epitaxial wafer, a method of manufacturing the epitaxial wafer, a diode, and a current rectifier. The epitaxial wafer comprises a Si substrate layer (11); an insulating layer (12) formed on the Si substrate layer (11); and a nitride semiconductor layer (13) formed on a surface of the insulating layer (12) facing away from the Si substrate layer (11); wherein the insulating layer (12) has a thickness configured such that under a forward bias voltage, the insulating layer (12) may allow electrons and holes to pass from one side to the other side of the insulating layer (12) via quantum tunneling so as to allow a forward current flow. Under reverse bias, the insulating layer (12) can hinder formation of free electrons and holes so as to block a reverse current. Thus, the epitaxial wafer is enabled to have the characteristic of allowing passage of a current only in one direction and can be made into a diode or the like for a current rectifying component.

Abstract: The application provides a reflective display device and a color laminated display device, and relates to the technical field of display. The reflective display device according to the present application includes: a first electrode which is a transparent electrode; a second electrode arranged opposite to the first electrode; a display layer arranged between an inner side of the first electrode and an inner side of the second electrode; the display layer including a plurality of pixel walls which are arranged in the display layer at intervals; and an accommodating cavity formed by two adjacent pixel walls and the inner side of the second electrode, the accommodating cavity being used for accommodating two color developing liquids, and each of the pixel walls has a color identical to the color developing liquid. Due to the fact that the color displayed by the pixel walls is the same as that displayed by the reflective display device, the color of external light passing through the pixel walls becomes the same as that of the reflective display device, so that influences of stray light on contrast ratio, color gamut and visual angle color cast of the reflective display device can be eliminated, thereby improving the color gamut and the contrast ratio of the reflective display device.
