A thin-film transistor includes a gate electrode made of metal, a light transmissive gate insulating film that covers the gate electrode, a semiconductor film that overlaps with the gate electrode through the gate insulating film, and a source electrode and a drain electrode, made of metal, and spaced from each other. The gate electrode and the semiconductor film have respective through-holes communicated with each other so that the gate insulating film enters an inside of the through-holes. The gate insulating film has an area of the inside of the through-holes of the gate electrode and the semiconductor film. The source electrode and the drain electrode pass through the inside of the through-holes of the gate electrode and the semiconductor film so as to overlap with a part of the area of the inside of the through-hole of the gate insulating film and avoid a remaining portion thereof.

Liquid crystal display device and method of manufacturing the same

Provided is a liquid crystal display device (), including a pixel electrode (Px) and a common electrode (CT) which are stacked via an insulating layer, one of the pixel electrode (Px) and the common electrode (CT) including slits (SL) formed therein, for aligning liquid crystal molecules by an electric field generated by the pixel electrode (Px) and the common electrode (CT), in which the insulating layer is formed so as to increase in thickness from a vicinity of ends () in a longitudinal direction of the slits (SL) toward the ends (). Thus, the transmittance of the liquid crystal display device is improved.

Liquid crystal display device

A liquid crystal display device includes a first substrate and a second substrate with a liquid crystal layer therebetween, a seal material joining the first substrate and the second substrate to each other, a plurality of gate signal lines and a plurality of drain signal lines, wherein the gate signal lines and the drain signal lines being formed on the first substrate, and a plurality of drive circuits connected to the first substrate. Data transmission signal lines are formed on the first substrate, wherein the data transmission signal lines are connected electrically between the drive circuits, and at least a part of at least one of the data transmission signal lines is positioned between the seal material and the first substrate.

Image display device

When one signal line group and another signal line group, which differs from the one signal line group in length, are arranged adjacent to each other, a disconnection due to static electricity which is caused by a spark generated between a signal line of the one signal line group and a signal line of the other signal line group can be prevented. For this purpose, the image signal line is specifically configured such that, on a substrate, a first signal line group in which a plurality of first signal lines are arranged in parallel and a second signal line group in which a plurality of second signal lines are arranged in parallel in a region arranged adjacent to the first signal line group are formed, and dummy lines are arranged between the first signal line group and the second signal line group.
