Abstract

This application relates to a display panel and a method for manufacturing same. The display panel includes an active switch array substrate. The display panel includes: a display region; a bezel region, including a gate drive region and a wiring region; and a polarizer, including a shied region, disposed on the active switch array substrate. The bezel region surrounds the display region and is located on a periphery of the display panel. The gate drive region is disposed on a periphery of the active switch array substrate. The shield region covers the gate drive region.

First claim

What is claimed is:

1. A display panel, comprising:
an active switch array substrate, comprising:
a display region;
a bezel region, comprising a gate drive region and a wiring region; and
a polarizer, comprising a shield region, disposed on the active switch array substrate, wherein
the bezel region surrounds the display region and is located on a periphery of the display panel, the gate drive region is disposed on a periphery of the active switch array substrate, and the shield region covers the gate drive region;
wherein the polarizer comprises a polarizing material layer, and a refractive index of the polarizing material is in a range of 2.0 to 3.2, and an extinction coefficient of the polarizing material is in a range of 2.7 to 3.5.

2. The display panel according to claim 1 , wherein the wiring region is spaced from the gate drive region.

3. The display panel according to claim 1 , wherein the shield layer is made of a hyperchromic light-absorbing material.

4. The display panel according to claim 3 , wherein the hyperchromic light-absorbing material is a black substance.

5. The display panel according to claim 4 , wherein a material of the black substance comprises a phenolic resin, a photosensitive compound, an organic colored polymeric dye, an inorganic colored dye, and a solvent, and the phenolic resin, the photosensitive compound, the organic colored polymeric dye, the inorganic colored dye, and the solvent are mixed with each other.

6. The display panel according to claim 1 , wherein a periphery of the polarizer is dehydrated and carbonized into a shield region after being pretreated by using a chemical reagent.

7. The display panel according to claim 6 , wherein the chemical reagent is a corrosive reagent.

8. The display panel according to claim 1 , wherein a periphery of the polarizer is carbonized into a shield region after a high-temperature and a high-pressure pretreatment.

9. A display panel, comprising:
an active switch array substrate, comprising:
a display region;
a bezel region, comprising a gate drive region and a wiring region; and
a polarizer, comprising a shield region, disposed on the active switch array substrate, wherein
the bezel region surrounds the display region and is located on a periphery of the display panel, the gate drive region is disposed on a periphery of the active switch array substrate, and the shield region covers the gate drive region, wherein
the wiring region is spaced from the gate drive region; and a periphery of the polarizer is carbonized into a shield region after being pretreated by using a chemical reagent or after high-temperature and high-pressure pretreatment;
wherein the polarizer comprises a polarizing material layer, and a refractive index of the polarizing material is in a range of 2.0 to 3.2, and an extinction coefficient of the polarizing material is in a range of 2.7 to 3.5.
