Abstract

A pixel circuit and a pixel structure having high aperture ratio are provided. A first gate electrode, a layer including a first source electrode and a first drain electrode, and an etching stopper layer, a first semiconductor layer, and a gate isolation layer sandwiched between the first gate electrode and the layer of the first source electrode and the first drain electrode construct a first thin film transistor. A second gate electrode, a layer including a second source electrode and a second drain electrode, and an etching stopper layer, a second semiconductor layer, and the gate isolation layer sandwiched between the second gate electrode and the layer of the second source electrode and the second drain electrode construct a second thin film transistor. A transparent electrode, a pixel electrode and a flat isolation layer sandwiched between the transparent electrode and the pixel electrode construct a transparent capacitor.
