Abstract

The invention provides an electrophoretic display assembly and a manufacturing method thereof. According to the invention, light leakage current is reduced and display effect is enhanced. The electrophoretic display assembly comprises a substrate, a grid line metal layer, a gate insulating layer, a semiconductor active layer, a data line metal layer, a photoresistance resin layer and a pixel electrode layer, wherein the grid line metal layer contains a grid and is formed on the substrate; the gate insulating layer covers the grid line metal layer; the semiconductor active layer is formed on the gate insulating layer and is correspondingly arranged above the grid; the data line metal layer contains a source electrode and a drain electrode and is formed on the gate insulating layer; the source electrode and the drain electrode are arranged on the semiconductor active layer at certain intervals; the photoresistance resin layer covers on the data line metal layer, and a through hole is formed above the drain electrode; and the pixel electrode is formed on the photoresistance resin layer and is connected with the drain electrode by virtue of the through hole. The electrophoretic display assembly and a manufacturing method thereof disclosed by the invention are applied to manufacturing of an electrophoretic display.

Description

technical field [0001] The invention relates to the technical field of electrophoretic display, in particular to an electrophoretic display component and a manufacturing method thereof. Background technique [0002] Electrophoretic display is a new type of display technology. It has the characteristics of both paper and electronic devices. It is not only in line with people's visual habits, but also convenient and fast. Electronic ink technology, one of the key technologies of electrophoretic display, is to suspend charged electrophoretic particles in a dispersion medium solvent to form a suspension system. Always change the displayed graphics and text. [0003] The electronic ink electrophoretic display is a reflective display device, which generally includes: a front cover with transparent electrodes, an electronic ink layer, and a thin film transistor (Thin Film Transistor, TFT) array substrate. Among them, the semiconductor active layer in the TFT array substrate is ge...
