In-plane switching mode TFT LCD pixel structure

The utility model discloses an in-plane switching mode TFT LCD pixel structure which comprises a substrate, a gate electrode, a silicon island, a source and drain electrode, a via hole protection layer and an electrode layer are sequentially arranged on the substrate, and a via hole is formed in the via hole protection layer and used for enabling the source and drain electrode and the electrode layer to be electrically connected. According to the utility model, the pixel electrode and the common electrode are positioned on the same layer by utilizing the principle of the ITO electric field on the same layer, and one mask is omitted, so that compared with the existing pixel structure with six masks, one mask and a process procedure matched with the mask can be omitted under the condition that the basic functions of the pixel structure are not influenced, and the production efficiency is improved. And therefore, the production period can be shortened. 本实用新型公开了一种面内开关模式TFT LCD像素结构，包括：基板，基板上依次设置有栅电极、硅岛、源漏极、过孔保护层及电
