Abstract: A liquid crystal display device includes a thin film transistor substrate, a counter substrate that faces the thin film transistor substrate, a liquid crystal composition that is arranged between the thin film transistor substrate and the counter substrate, an oriented film that arranges orientation of the liquid crystal composition contacting with the thin film transistor substrate, a seal material that seals the liquid crystal composition between the two substrates, and a driver circuit. The driver circuit has a light transmission area that is formed inside of the driver circuit, and is higher in light transmittance than an area in which a non-transparent conductive film forming the driver circuit is formed, and a high sealing property area in which the seal material and an insulating film come into direct contact with each other between the light transmission area and an outer edge of the thin film transistor substrate.

Abstract: A gate signal line driving circuit which suppresses noises in a gate signal and a display device which uses the gate signal line driving circuit are provided. A first basic circuit provided to a gate signal line driving circuit includes a HIGH voltage applying switching element which applies a HIGH voltage to gate signal lines in response to a signal HIGH period, and a LOW voltage applying switching circuit which applies a LOW voltage to the gate signal lines in response to a signal LOW period. In response to a signal HIGH period, a switch of the LOW voltage applying switching circuit of the first basic circuit is turned off based on a signal applied to a switch of the HIGH voltage applying switching element of a second basic circuit which assumes a signal HIGH period earlier than the first basic circuit.
