Abstract

The invention discloses an array substrate and a liquid crystal display device. The array substrate comprises multiple parallel data cables and multiple scanning lines which perpendicularly insect with the data cables, and the data cables and the scanning lines are insulated at the junction; the array substrate further comprises pixel electrodes, and each pixel electrode is driven by n thin film transistors which share the same data cable and the same scanning line, wherein n is a positive integer larger than or equal to 2. The liquid crystal display device comprises the array substrate. According to the array substrate and the liquid crystal display device, compared with the prior art, the technical problem that pixel electrodes of an existing array substrate are low in charging efficiency is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an array substrate and a liquid crystal display device. Background technique [0002] In existing thin film transistor liquid crystal display devices, thin film transistors are key components. In order to achieve better display quality, it is necessary to continuously improve the characteristics of thin film transistors. Increasing the width-to-length ratio of the channel of the thin film transistor to increase the turn-on current of the thin film transistor is currently a research direction. However, the width-to-length ratio of the channel of the thin film transistor is limited by the manufacturing process of the thin film transistor, so the degree of increasing the turn-on current is limited, which leads to low charging efficiency of the pixel electrode. Contents of the invention [0003] The invention provides an array substrate and a liquid crystal display device. C...
