Embodiment Construction

[0042] figure 2 It is a schematic plan view of a polarizer embodiment of the present invention, image 3 for figure 2 A view in the A-A' direction, such as figure 2 , image 3 As shown, the polarizer includes a glass substrate 51 and a metal wire grid 52 disposed on the glass substrate 51 . The metal wire grid 52 is formed by parallel arrangement of metal wires 53 on the glass substrate 51 . The line width of the metal wire 53 is less than or equal to one-third of the wavelength of the incident light, and when it is one-tenth of the wavelength of the incident light, the polarization effect of the polarizer is the best. In this embodiment, the line width of the metal lines 53 may be 50 nm to 150 nm, and the period, which is the line width of the metal lines 53 plus the distance between the metal lines 53 , may be 100 nm to 300 nm. The wire height of the metal wire may be 100nm-200nm. The metal wire 53 can be made of copper, aluminum and other metals with high conductiv...

Abstract

The invention relates to a polarizer, a manufacturing method thereof, and a liquid crystal display device. The polarizer includes a glass substrate and a metal wire grid arranged on the glass substrate. The liquid crystal display device is provided with the polarizer, which greatly reduces the cost of the polarizer and the liquid crystal display device, and the polarizer does not absorb the incident light, greatly reduces the loss of light energy passing through the polarizer, and improves the utilization rate of light energy . The method comprises: placing the cathode electrode and the anode electrode in parallel on a glass substrate; connecting the cathode electrode and the anode electrode to a DC power supply; dropping a solution containing metal cations between the cathode electrode and the anode electrode; placing Another glass substrate; adjust the temperature of the solution until the solution freezes; adjust the temperature to produce a liquid layer between a glass substrate and the ice; supply power to the cathode electrode and the anode electrode to obtain a polarizer, which greatly simplifies the manufacturing process of the polarizer and reduces Manufacturing costs of polarizers.

Description

technical field [0001] The invention relates to display technology, in particular to a polarizing plate capable of reducing the cost of the polarizing plate and improving the utilization rate of light energy, a manufacturing method thereof, and a liquid crystal display device. Background technique [0002] In recent years, with the rapid development of display technology, color liquid crystal display devices have been more and more widely used in people's daily life and production, especially small-sized color liquid crystal display devices, which are used in mobile phones, personal digital assistants (Personal Digital Assistants) Assistant, PDA), Global Positioning System (GPS), e-books, digital cameras and other fields have developed rapidly. Among them, the brightness, contrast, viewing angle and other characteristics of the color liquid crystal display device are display indicators that have attracted much attention. [0003] In terms of brightness, since the liquid cry...
