LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE:To obtain a display with high quality in the moving picture display without complicated picture processing by revising the picture display for each field. CONSTITUTION:A liquid crystal drive signal is inputted to a horizontal scanning circuit 121 to input a control signal Gdel to a control signal Gd3l input terminal and to input an erasure signal Vdel to an erasure signal Vdel input terminal. When a signal Vgatel whose pulse width is a signal supply period Tsig is outputted in an odd number field, a TFT (thin film transistor) 103 of a 1st row of a scanning electrode X is turned on and a signal electrode signal Vs for the signal supply period Tsig is fed to a picture element electrode 105. When a signal Vgatel whose pulse width is a signal erasure period Tdel is outputted in an even number field, the TFT 103 of the 1st row of the scanning electrode X is turned on and the signal electrode signal Vs for the signal erasure period Tdel is fed to the picture element electrode 105 and the picture of the 1st row of the scanning electrode X is erased.
