显示基板及其制备方法、显示装置
By setting a light-shielding layer on the array substrate to cover the reflective layer interval area and matching it with the common electrode potential of the opposing substrate, the problem of reduced reflective aperture ratio caused by the black matrix is solved, and a better display effect is achieved.

AI Technical Summary
Technical Problem
In the prior art, transflective LCD panels suffer from poor display brightness due to the reduced reflectivity caused by the black matrix on one side of the color filter substrate.
Method used
A light-shielding layer is set on the array substrate to cover the interval area of the adjacent reflective layer, and the light-shielding layer and the common electrode potential of the opposing substrate are the same when the black state is displayed to avoid the formation of a vertical electric field, thus eliminating the black matrix setting on the opposing substrate side.
Benefits of technology
The increased aperture ratio prevents light leakage and ensures better display performance.

Abstract
提供了一种显示基板及其制备方法、显示装置，属于显示技术领域。该显示基板中的阵列基板包括：衬底，位于衬底一侧且相互间隔的多个像素，以及位于每相邻两个像素的反射层间隔区的遮光层。其中，遮光层在衬底上的正投影覆盖间隔区在衬底上的正投影，且反射层在衬底上的正投影与遮光层在衬底上的正投影交叠。如此，可以在间隔区形成遮光结构实现遮光，避免发生漏光。在此基础上，与阵列基板相对的对置基板一侧对应该间隔区的位置即无需设置黑矩阵。如此，可以确保反射开口率较大，从而确保显示效果可以较好。
