Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises an array substrate, a backlight source and an array substrate polarizer. The array substrate hasmultiple thin film transistors; the backlight source is arranged under the array substrate and is used for providing a light source; and the array substrate polarizer is arranged to the side, facing to the backlight source, of the array substrate, and has light shielding portions, wherein the light shielding portions are corresponding to the thin film transistors. The manufacturing method of the display panel comprises the following steps: preparing the array substrate; preparing the array substrate polarizer; attaching the array substrate polarizer; and attaching the backlight source. By removing a shielding layer (LS) on an existing array substrate, flatness of the lower portion of a semiconductor channel region of the thin film transistor is maintained; by adding the light shielding portions onto the array substrate polarizer corresponding to the thin film transistors, the semiconductor channel region of the thin film transistor can be prevented from being influenced by light; and production cost and time can be saved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a manufacturing method thereof. Background technique [0002] At present, the array substrate of low-temperature polysilicon (LTPS) products is composed of a separate switching element thin film transistor (Thin Film Transistor, TFT), a storage capacitor (Cst) and a pixel transparent electrode (Pixel Electrode). The semiconductor performance of the thin film transistor is enhanced by ion implantation. Under the action of the electric field of the scanning line (Gate), the charging and discharging process of the pixel transparent electrode (Pixel Electrode) is realized, and the voltage of the plate under the storage capacitor (Cst) is adjusted to control the rotation angle of the liquid crystal molecules, so as to realize the colorful display effect of the liquid crystal display product . [0003] However, the low-temperature polysilicon array substrates of the existing li...
