Problems solved by technology
However, after the rotation, the viewing angle of the 3D grating will be deflected accordingly, which deviates from the best direction for human eyes to watch (this direction is generally the 6 o'clock direction, that is, directly in front of the line of sight), resulting in poor viewing angle characteristics of 3D display

Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a 3D display device. Background technique [0002] At present, most of the grating-type (barrier) glasses-free 3D technologies use a TN-type grating structure, and its viewing angle is basically the same as that of a common twisted nematic (TN) display. However, most of the display screens that match the TN grating structure are wide viewing angle display screens that use wide viewing angle technology, such as: plane switching IPS, edge field switching technology ADS display). In the wide viewing angle display, the transmission axes of the upper polarizer and the lower polarizer are perpendicular to each other, the orientation direction of the upper alignment layer (the alignment layer on the color filter substrate) and the lower alignment layer (the alignment layer on the array substrate) are opposite, and the lower alignment layer (the alignment layer on th...
