Abstract:
1. A pixel structure, comprising: a scan line and a data line; an active device, electrically connected to the scan line and the data line; a pixel electrode, electrically connected to the active device; a capacitor electrode line, located underneath the pixel electrode, wherein the capacitor electrode line and the pixel electrode constitute a first storage capacitor having a first storage capacitance; a semi-conductive pattern layer, disposed between the capacitor electrode line and the pixel electrode, wherein the pixel electrode is electrically connected to the semi-conductive pattern layer, and the semi-conductive pattern layer and the capacitor electrode line constitute a second storage capacitor having a second storage capacitance; a reference electrode pattern layer, disposed between the pixel electrode and the semi-conductive pattern layer, wherein the reference electrode pattern layer is electrically insulated with the pixel electrode and constitutes a third storage capacitor having a third storage capacitance with the pixel electrode; at least one dielectric layer, disposed between the capacitor electrode line and the pixel electrode, disposed between the semi-conductive pattern layer and the capacitor electrode line, and disposed between the reference electrode pattern layer and the pixel electrode, wherein the at least one dielectric layer comprises: a reference electrode line, electrically connected to the reference electrode pattern layer, a first contact window, disposed in the second dielectric layer; a second contact window, disposed in the first dielectric layer and the second dielectric layer; and a connecting layer, electrically connected to the reference electrode pattern layer and the reference electrode line respectively through the first contact window and the second contact window, such that the reference electrode pattern layer and the reference electrode line are electrically connected, wherein a total storage capacitance is the sum of the first storage capacitance, the second storage capacitance and the third storage capacitance, and the second storage capacitance occupies 30%-80% of the total storage capacitance.
