Abstract: The present disclosure provides an array substrate, a liquid crystal display panel and a liquid crystal display device, including: a base substrate; gate lines each extending in a first direction on the base substrate; data lines each extending in a second direction intersecting the first direction; pixel units located in regions defined by the gate lines and the data lines; each pixel unit has a first side and a second side each extending in the second direction and opposite to each other in the first direction; each pixel unit includes a first electrode including a plurality of strip-shaped 10 electrodes, at least part of the strip-shaped electrodes each have a first part and a second part extending in different directions, first parts are connected at the first side, second parts are disconnected at the second side, and lengths of the first part and the second part are different.

Abstract: An optical element includes a substrate and a pattern. The substrate has a top surface and a bottom surface. The pattern is provided on the top surface. The pattern includes multiple levels such that a thickness of the pattern is less than a design wavelength. The pattern is configured to focus an incident radiation, received at one of the top surface or the bottom surface of the substrate, at one or more prescribed focal locations on a detection plane. The one or more prescribed focal locations on the detection plane changes in proportion to a wavelength of the incident radiation. The detection plane is an achromatic focal plane when the incident radiation includes multiple wavelengths.
