Abstract: Disclosed is a high-definition liquid crystal display device wherein a video signal applied to the pixel electrode is compensated for a gain decrease in a high frequency range. A video signal processing circuit includes an inversion processing circuit which outputs at least one video signal inputted to a source driver circuit. The inversion processing circuit includes an amplifier and has function of amplification and inversion. A peaking processing circuit is connected to an amplifier in the inversion processing circuit.

Also, the top plate may be detachably coupled to the base plate, advantageously by double stick adhesive tape, so that only the top plate is replaced when damaged.
