Abstract: The present application provides a display device, when the display device is in a first display mode, a transmittance of first optical units to light is less than a transmittance of second optical units to light, so that diffracted light is emitted due to a phenomenon that apertures in a diffraction panel are alternating between light and dark. After the diffracted light emitted by the diffraction panel passes through a display panel, the display device has a wide viewing angle in the first display mode.

Abstract: A display panel and a display device are disclosed. In preparing the display panel, based on a height difference formed between a plurality of first column spacers and a plurality of second column spacers, as a color filter substrate deforms during a vacuum assembly process, a deformation area of a blind hole area increases because the second column spacers are not in contact with an array substrate in the blind hole area, resulting in a decrease in a radius of curvature of the deformation of the blind hole area, so that an amount of deformation is reduced and poor focusing due to Newton's ring effect on the blind hole can be prevented.

Abstract: A gate driver on array (GOA) circuit and a display panel are provided. The GOA circuit provides a pull-up maintaining module including transistors T11, T12, and T13. In a pre-charge sub-phase t1 and an output sub-phase t2, a node Qb is at a high level to pull down a node P and turn off the transistor T13. A node K changes to the high level under control of the transistor T11. The transistor T12 is turned on, and the node Qb is keeping at the high level. A node Qa is keeping at the high level in the pre-charge sub-phase, and keeping at a bootstrap electrical level in the output sub-phase.
