<p>PURPOSE:To provide a liquid crystal display device in which high-quality display is achieved in spite of the dispersion of respective component parts, which is inevitable as a matter of the production of the liquid crystal display device. CONSTITUTION:An active driving circuit 13a and a photosensor 13b which detects light transmitted through a transference electrode 13 are assembled in the transference electrode 13 on an array substrate, and a feedback amplifier 14 which inputs the voltage of a signal line 8 giving the driving voltage to the electrode 13 and output from the photosensor 13b is provided in the active driving circuit 13a, then the driving voltage is made proper in the amplifier 14 according to the output from the photosensor 13b.</p> |
