Array substrate, liquid crystal display panel and display device

Abstract

The invention provides an array substrate, a liquid crystal display panel and a display device. The array substrate comprises a substrate, a plurality of scanning lines, a plurality of thin film transistors arranged in a matrix form, a flattening layer, a filling electrode and a pixel electrode, wherein the scanning lines and multiple pieces of data are arranged in a cross manner; each thin film transistor comprises a gate, an active layer and a drain electrode; the flattening layer covers the gate, the active layer and the drain electrode; a through hole penetrating through the flattening layer is formed in a position, which corresponds to the drain electrode, of the flattening layer; the drain electrode is positioned inside the through hole; the filling electrode is positioned in the through hole, is connected with the drain electrode and covers the drain electrode; the pixel electrode is indirectly connected to the drain electrode through the filling electrode. According to the array substrate disclosed by the invention, the distance between the data line and the pixel electrode is enlarged, the influence of the data line on the pixel electrode is reduced, and a crosstalk phenomenon of the display device is improved; a segment gap of the drain electrode is compensated through the filling electrode, the line breakage problem of the pixel electrode is improved, and the yield of the display device is improved.

Description

technical field

[0001] The invention relates to the field of display technology, and in particular to an array substrate, a liquid crystal display panel and a display device. Background technique

[0002] With the rapid development of display technology, touch display devices have gradually pervaded people's lives. In the initial stage of the development of touch display, the touch display panel is formed by laminating the touch panel and the display panel to realize the touch display. The touch panel and the display panel need to be prepared separately, which is costly and relatively thick. Low production efficiency. With the development of touch display technology, an in-cell touch display panel has appeared. The in-cell touch display panel embeds the touch electrodes inside the display panel, which can reduce the overall thickness of the module and greatly reduce the The production cost of the touch display device makes it favored by major panel manufacturers.
