Embodiment Construction

[0021] figure 1 Shown is a polarizer 10 prepared according to the method of the present invention, which includes: a protective film 11, a polarizing film 12 formed on the protective film 11, an alignment layer 13 formed on the polarizing film 12, and A liquid crystal compensation layer 14 formed on the alignment layer 13 .

[0022] The protection film 11 provides support and protection functions for the polarizing film 12 and is made of triacetyl cellulose (TAC). Alternatively, the protective film may be made of cellulose-based resins such as propionyl cellulose, polyamide-based, polycarbonate-based, polyester-based, polystyrene-based, polyacrylic-based, polynorbornene-based, and other transparent resins.

[0023] The polarizing film 12 is stretched in a specific direction with a thin sheet of PVA material, and is dyed with iodine (I 2 dying) process, so that it has the function of filtering light with partial polarity.

[0024] The main material of the alignment layer 13 ...

Abstract

The present invention provides a polarizer having phase compensation function at the same time, including a protecting film, a polarizing film formed on the protecting film, an alignment layer formed on the polarizing film, and a liquid crystal compensation layer formed on the alignment layer.

Description

technical field [0001] The present invention relates to an optical film, in particular to a polarizer for a liquid crystal display panel with a phase compensation function and a manufacturing method thereof. Background technique [0002] The liquid crystal display panel achieves the purpose of optical switching by using a liquid crystal cell that can transform the optical transmission characteristics by an electric field, and cooperates with a polarizer that filters light with polarity. [0003] However, whether it is a liquid crystal material with optically anisotropy itself, or a polarizer that uses external force to change the structure and add substances to produce optical anisotropy, it will have different refractive index directions due to the , leading to inconsistencies in the display quality presented by the liquid crystal display panel in different viewing angle directions. [0004] Generally speaking, in order to improve the above-mentioned display quality proble...
