Abstract

The invention provides a liquid crystal display device which comprises a short circuiting bar area, a periphery area and a display area, wherein the short circuiting bar area comprises a plurality of detection terminals, each detection terminal is connected with a plurality of short circuiting bars, each short circuiting bar is connected with a plurality of connecting lines, each connecting line is electrically connected with the detection terminals through at least two signal transmission channels; the periphery area is electrically connected with the short circuiting bar area; and the display area is electrically connected with the periphery area. Due to the fact that each connecting line is electrically connected with the detection terminals through at least two signal transmission channels in the liquid crystal display device, even if one signal transmission channel breaks, the detection operation can be carried out through the other signal transmission channel, reliability of the liquid crystal display device is improved, and wire arrangement reliability in the short circuiting bar area is improved particularly.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a liquid crystal display device. Background technique [0002] The liquid crystal display device includes a display area composed of matrix display pixels, the display area has a plurality of gate lines extending in the row direction of the display pixels and a plurality of data lines extending in the column direction of the display pixels. Wire. Switching elements and pixel electrodes connected to the switching elements are provided at the intersections of these gate lines and data lines. The switching elements are, for example, thin film transistors (switching elements). The signal from the pole line and the signal from the data line are sent to each corresponding pixel electrode. [0003] The liquid crystal display device further includes a peripheral area, and the peripheral area includes data lines arranged in a fan shape and gate lines arranged in a fan shape. One end of t...
