Abstract

The invention discloses a pixel unit structure, an array structure and a liquid crystal display device to solve the problem of poor display effect of a liquid crystal display device in the prior art. The pixel unit structure comprises a first electrode, a second electrode and shielding electrodes, the first electrode is of a faceted structure, a first insulating layer is formed on the first electrode, the second electrode is formed on the first insulating layer and comprises a plurality of strip electrodes which are arranged at intervals, and the shielding electrodes are arranged at the tail ends of the strip electrodes of the second electrode. By the aid of the technical scheme, when the pixel unit structure has electric signals, an Ey-direction electric field generated at the tail ends of the strip electrodes of the second electrode is shielded owing to the shielding electrodes, so that domain lines are effectively avoided, display molecules corresponding to all display areas of the pixel unit structure can rotate according to a preset mode, and image display effects are improved.

Description

technical field [0001] The invention relates to the field of display device manufacturing, in particular to a pixel unit structure, an array structure and a liquid crystal display device. Background technique [0002] With the rapid development of science and technology, the performance of display devices of electronic products has been greatly improved, and various large-size, high-resolution display devices have been widely used. [0003] Currently, display devices generally adopt TN (Twisted Nematic, twisted nematic) display mode, ADS (ADvanced Super Dimension Switch, advanced super dimension field switching technology) display mode and FFS (Fringe Filed Switching; fringe field switching technology) display mode. [0004] The FFS display mode is favored by the market due to its advantages such as large viewing angle and high light transmittance. However, in the FFS display mode in the prior art, display abnormalities may occur on the side of the pixel unit away from the ...
