Abstract

The invention discloses a liquid crystal display. Peripheral leads of the liquid crystal display are arranged in the same conductive layer, so that the signal delays of the peripheral leads are only related to the resistances of the peripheral leads; each peripheral lead is connected with two scanning lines by two resistance-trimming thin film transistors respectively; the resistance Ri of the ith resistance-trimming thin film transistor is preset to be a fixed value; the resistance of the corresponding peripheral lead is RiL; and the resistance Rn of any other nth resistance-trimming thin film transistor and the resistance RnL of the peripheral lead corresponding to the nth resistance-trimming thin film transistor meet the equation that Rn + RnL are equal to Ri + RiL. The resistance Rn of the nth resistance-trimming thin film transistor can compensate the signal delay of the nth peripheral lead, so that the signal delays of the nth peripheral lead and the ith peripheral lead are the same, finally the signal delays of all the peripheral leads and the signal delay of the ith peripheral lead are the same, the liquid crystal display is prevented from cross grains, and the display effect is improved.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] The information society increasingly needs thin and portable display devices, and the most mature product at present is a liquid crystal display device (Liquid Crystal Display, LCD). [0003] However, when the existing LCD displays pictures, horizontal stripes often appear, which reduces the display effect of the LCD. Contents of the invention [0004] In view of this, the object of the present invention is to provide a liquid crystal display device to solve the problem of horizontal stripes and poor display effect in the existing liquid crystal display device. [0005] The liquid crystal display device includes: [0006] A thin film transistor substrate, the thin film transistor substrate includes a display area and a non-display area, and a plurality of scanning lines, a plurality of data lines and a plural...
