A liquid crystal display device is disclosed. The liquid crystal display device includes a display panel that includes four sides. One of the four sides has a cut edge. The display panel includes a display region in which an image is to be displayed; a non-display region that surrounds the display region and that includes a non-light transmitting layer that restricts light transmission therethrough; and a plurality of slits disposed in the non-light transmitting layer. An edge of the non-light transmitting layer is co-planar with the cut edge. The plurality of slits are parallel to the cut edge.

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

In a liquid crystal display device, each pixel region formed over a liquid crystal side of one substrate out of respective substrates which are arranged to face each other with liquid crystal therebetween includes pixel electrodes to which a video signal is supplied from a drain signal line through a switching element driven in response to a scanning signal from a gate signal line and capacitive elements which are formed between the pixel electrodes and a capacitive signal line by way of a dielectric film. In such a constitution, the pixel region is divided into a plurality of regions, and video signals are supplied to respective pixel electrodes and capacitive elements in respective regions through paths which are branched from the switching element.

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.
