    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 plurality of cascade-connected register circuits which comprises a bidirectional shift register include a top register circuit, a bottom register circuit, and main register circuits. The register circuit has an output circuit which outputs one of four-phase clock pulses when a voltage of a first node is an active level; a second output circuit which outputs a non-active level when a voltage of a second node is the active level; a second node reset circuit which sets the second node to the non-active level when a voltage of a second node reset terminal is the active level. The forward scan signal sets the voltage of the first node of the top register circuit to the active level, and the forward scan signal sets the voltage of the second node reset terminal of the bottom register circuit to the active level.

    Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.
