The invention discloses a bidirectional scan electric charge sharing type pixel structure which comprises a plurality of pixel units crosswise limited by a plurality of scanning lines and data lines. Each sub-pixel unit comprises a first sub-pixel and a second sub-pixel, wherein the first sub-pixel comprises a first transistor connected with a first scanning line and the correspongding data line, and a fourth transistor connected with a first voltage-dividing capacitance and the first transistor. Each second sub-pixel has the same design as the corresponding first sub-pixel, and comprises a second transistor, a third transistor and a second voltage-dividing capacitance. When the pixel structure is scanned, the first transistors and the second transistors are started at the same time. When the third transistors or the fourth transistors are started, capacitancesecond gray scale voltages of the second sub-pixels or first gray scale voltages of the first sub-pixels are changed. Through the voltage-dividing capacitances arranged on the first sub-pixels and the second sub-pixels, not only can eight-domain display be achieved, but also bidirectional scanning can be achieved.
