Abstract

The invention discloses a display panel and a display device. The display panel comprises a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer arranged between the first substrate and the second substrate, a pixel electrode, a public electrode and an alignment layer. The liquid crystal layer is composed of liquid crystal molecules with dielectric constant anisotropy being negative, the pixel electrode and the public electrode are located on the first substrate and insulated from each other, the alignment layer covers the pixel electrode and the public electrode and has a preset alignment direction, the pixel electrode comprises at least two branch electrodes and an end electrode connecting the ends of the branch electrodes, each branch electrode comprises a body portion and a bend connection portion, each bend connection portion is connected between the corresponding body portion and the end electrode, and a first angle formed between each bend connection portion and the alignment direction is larger than or equal to 5 degrees and smaller than or equal to 25 degrees. The display panel and the display device can solve the phenomenon that pressing display of the display panel is not uniform, the penetration rate is increased along with reducing of a bend angle, drive voltage is lowered, and therefore power consumption is lowered.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device including the display panel. Background technique [0002] Liquid Crystal Display (LCD) is a display made of liquid crystal material, which has the characteristics of light and thin, low power consumption and large amount of displayed information. An LCD generally includes a liquid crystal display panel for displaying pictures and a circuit part for supplying signals to the liquid crystal display panel. The liquid crystal display device generally includes a first substrate and a second substrate, which are bonded to each other by a sealant and separated by a gap, and liquid crystal material is filled in the gap between the first substrate and the second substrate. [0003] The widely used liquid crystal display modes include twisted nematic mode (Twist Nematics, TN), vertical alignment mode (Vertical Alignment, VA), in-plane flipping...
