Abstract

See full text

An image display device, a scan line drive circuit and a driver circuit for the display device capable of driving the display device having a multiplex pixel structure by simple control and utilizing a simplified gate driver. The image display device includes a plurality of pixel electrodes, a plurality of scan lines G for supplying scan signals to turn on and off these pixel electrodes, a pulse generator for generating a shift pulse, buffers B provided corresponding to the respective scan lines G, and a shift register unit in which first and second shift registers SR1 and SR2 are alternately cascade-connected. The shift pulse is propagated through the first and the second shift registers SR1 and SR2 by outputting the shift pulse from the pulse generator to the shift register unit. In this way, the shift pulse is controlled to be propagated between a buffer B to an adjacent buffer B in one horizontal scanning cycle.
