Abstract

The present invention discloses a pixel unit and an array substrate. The pixel unit comprises a data line, a gate line, a thin-film transistor, and a pixel electrode containing at least two domains, wherein the thin-film transistor is connected to the data line, the gate line, and the pixel electrode, respectively; and the pixel electrode further comprises at least one bucking electrode disposed parallel to the edge of the pixel electrode, with the bucking electrode being electrically connected to the pixel electrode. In such a manner, the pixel unit is able to shield interference of peripheral electric fields with the pixel electrode, allowing for more stable electrode field at the marginal area of the pixel electrode, thereby avoiding dark fringes present in the marginal area of the pixel electrode.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a pixel unit and an array substrate. Background technique [0002] In the design of conventional pixel electrodes, openings are usually designed in the edge area of ​​the pixel electrodes to assist the arrangement of liquid crystals in the light-transmitting area. However, when the edge area of ​​the pixel electrode adopts an opening design, due to the existence of parasitic capacitance, the electric field generated by the metal layer close to the pixel electrode is likely to interfere with the electric field of the pixel electrode, making the potential of the pixel electrode unstable, and the pixel electrode The problem of dark lines appearing in the edge area of ​​. [0003] Wherein, the metal layer close to the pixel electrode includes a first metal layer and a second metal layer, the first metal layer is used to make gate lines, common electrode lines, etc., and the sec...
