Abstract: The present invention provides a LTPS array substrate and a manufacturing method thereof. The method comprises: forming a source electrode and a drain electrode on a substrate, forming polysilicon layers of a first region and a second region on the substrate including the source electrode and the drain electrode, and the thickness of the polysilicon layer of the first region is greater than the one of the second region, the polysilicon layer of the first region partially covers the source electrode and the drain electrode; passivating the surface of the polysilicon layer in order to turn the part of the adjacent surface of the polysilicon layer of the second region and the first region into an insulating layer; forming a gate electrode on the insulating layer between the source electrode and the drain electrode. The present invention can simplify the LTPS technical process and reduce the producing costs.

Abstract: The disclosure provides a liquid crystal display device and a method for manufacturing a light guiding plate thereof. Wherein, multiple first protrusions are disposed on an irradiating surface of the light guiding plate, a prism sheet of an optical film assembly is disposed adjacent with the light guiding plate, multiple of second protrusions are disposed on the prism sheet of the optical film assembly, the second protrusions and the first protrusions are alternatively arranged, and translucent adhesives are disposed between each of the first protrusions and two adjacent second protrusions, such that the prism sheet is fixed with the light guiding plate. The disclosure can improve the phenomena of Hotspot Mura when displaying and decrease the thickness of the backlight module, such that it is beneficial for the designs of narrow frame and non-frame of liquid crystal display devices.
