Embodiment 1
[0053] S201, such as image 3 and Figure 4a As shown, the surface of the base substrate 01 is coated with a first polymer monomer 101 composed of an acrylic monomer.
[0054] S202, such as Figure 4b As shown, the first mask 201 is disposed on the surface of the first polymer monomer 101 , and the position of the first polymer monomer 101 corresponding to the light-transmitting area A of the first mask 201 is exposed to ultraviolet rays.
[0055] Wherein, the first mask plate 201 also includes a light-shielding region B that is opaque. In this way, under the shading of the light-shielding area B, the first polymer monomer 101 corresponding to the position of the light-shielding area B will not be cured by ultraviolet light.
[0056] S203, such as Figure 4c As shown, the first polymer monomer 101 corresponding to the light-shielding region B of the first mask 201 is removed to form a pattern of first protrusions 110 arranged at intervals.
[0057] Specifically, since the...

Abstract
The embodiment of the invention provides a wire gridpolarizer, a manufacturing method of the wire gridpolarizer and a display device, and relates to the field of display technologies. According to the manufacturing method of the wire gridpolarizer, the problem that a wire grid polarizer is high in production cost in the manufacturing process is solved. The manufacturing method of the wire grid polarizer includes the steps that the surface of a base plate of a substrate is coated with a first polymermonomer; curing process is carried out on the first polymermonomer corresponding to a preset position; patterns of first protrusions arranged at intervals are formed on the surface of the base plate of the substrate; the surface, where the first protrusions are formed, of the base plate is coated with mixtures of a second polymermonomer and metal particles; curing process is carried out on the mixtures corresponding to the preset position; wire grid patterns composed of second protrusions arranged at intervals are formed on the surface of the base plate of the substrate; at least one polarizing surface of each first protrusion is covered with the corresponding second protrusion.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a wire grid polarizer, a manufacturing method thereof, and a display device. Background technique [0002] TFT-LCD (Thin Film TransistorLiquid Crystal Display, Thin Film TransistorLiquid Crystal Display), as a flat paneldisplay device, has become more and more popular due to its small size, low power consumption, no radiation and relatively low production cost. It is widely used in the field of high-performance display. [0003] TFT-LCD such as Figure 1a As shown, it is composed of an array substrate 10 and a color filter substrate 11 . A liquid crystal layer 12 is disposed between the array substrate 10 and the color filter substrate 11 . In addition, a first polarizer 13 is disposed on the upper surface of the color filter substrate 11 , and a second polarizer 15 is disposed between the array substrate 10 and the backlight module 14 . Wherein, the optical axes of the fi...
