Title: DISPLAY PANEL AND MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE DISPLAY
Abstract:
The present invention relates to the field of photoelectric technology. Provided are a display panel and a manufacturing method thereof and a display device capable of reducing reflection of ambient light entering a display panel. The display panel comprises an AMOLED luminescent panel (1) and a light-filtering layer provided at a cathode surface (10) of the AMOLED luminescent panel (1). The light-filtering layer comprises a color filter (2) and a diffuser film (3). The color filter (2) comprises a red color filter unit, a green color filter unit, a blue color filter unit, and a BM. The diffuser film (3) is provided at one surface of the color filter (2), or at each filter unit of the color filter (2). The diffuser film (3) is used to cause ambient light passing therethrough to be emitted toward the cathode surface (10) of the AMOLED luminescent panel (1) in a direction not perpendicular to the cathode surface (10) of the AMOLED luminescent panel (1), such that the ambient light is reflected by the cathode surface (10) of the AMOLED luminescent panel (1) to the BM, or to the filter unit having a color different from a color of the filter unit through which the ambient light passes.
