阅读说明：本技术 显示基板及其制作方法、显示面板和显示装置 (Display substrate, manufacturing method thereof, display panel and display device ) 是由 魏玉龙 张震 于 2019-12-20 设计创作，主要内容包括：一种显示基板及其制作方法、显示面板和显示装置。所述显示基板包括衬底基板,以及依次位于所述衬底基板上的遮光层(S1)和薄膜晶体管阵列层；遮光层(S1)包括多个成像小孔(H1)；遮光层(S1)与薄膜晶体管阵列层之间设置有第一保护层(P0)；衬底基板上设有第一区域,薄膜晶体管阵列层包括的金属膜层在衬底基板上的正投影设置于所述第一区域之外；成像小孔(H1)在衬底基板上的正投影的至少一部分设置于所述第一区域内；第一保护层(P0)在衬底基板上的正投影至少覆盖第一区域的一部分；第一区域包括小孔区域(A0)；第一保护层(P0)在衬底基板上的正投影至少覆盖小孔区域(A0)；所述显示基板还包括缓冲层(Bf)。所述的显示基板及其制作方法、显示面板和显示装置能提升指纹识别效果。(A display substrate, a manufacturing method thereof, a display panel and a display device are provided. The display substrate comprises a substrate, and a light shielding layer (S1) and a thin film transistor array layer which are sequentially arranged on the substrate; the light-shielding layer (S1) includes a plurality of imaging apertures (H1); a first protective layer (P0) is arranged between the shading layer (S1) and the thin film transistor array layer; the substrate base plate is provided with a first area, and the orthographic projection of a metal film layer included by the thin film transistor array layer on the substrate base plate is arranged outside the first area; at least a portion of an orthographic projection of the imaging aperture (H1) on the substrate base is disposed within the first region; an orthographic projection of the first protective layer (P0) on the base substrate covers at least a part of the first area; the first region comprises an aperture region (a 0); an orthographic projection of the first protective layer (P0) on the substrate base plate at least covers the small hole area (A0); the display substrate further includes a buffer layer (Bf). The display substrate, the manufacturing method of the display substrate, the display panel and the display device can improve the fingerprint identification effect.)
