Abstract

The invention discloses a pixel unit, which comprises a gate line, a source line, a drain line, an active element and a pixel electrode. The active element is electrically connected with the gate line, the source line and the drain line. The pixel electrode comprises a trunk line and multiple strip-shaped electrodes. The trunk line is electrically connected with the drain line and forms a first pre-set angle with a first polarizing axis or a second polarizing axis. The trunk line has two subsections at least. One end of each strip-shaped electrode is connected with the trunk line and each strip-shaped electrode and the trunk line form a second pre-set angle. The invention also discloses an LCD panel.

Description

【Technical field】 [0001] The present invention relates to a liquid crystal display device, in particular to a pixel unit in a display device; [0002] The present invention also relates to a display panel, in particular to a liquid crystal display panel. 【Background technique】 [0003] In the pixel area of ​​an existing liquid crystal panel, a transparent conductive electrode with a cross-shaped pattern is generally used as the backbone, and the strip electrode and the backbone have an angle of 45 degrees. vertical, such as figure 1 As shown, due to the deflection effect of the liquid crystal, a cross-shaped dark area corresponding to the trunk will appear in the pixel area, which affects the display effect of the liquid crystal panel. [0004] In addition, the deflection direction of the liquid crystal is continuously changed, and the electric field generated by the middle area of ​​the trunk of the pixel electrode is different from the edge area. If the trunk of the pixe...
