Embodiment Construction

[0029] refer to Figure 2 to Figure 4 In order to obtain a liquid crystal display device in which the outgoing light is linearly polarized or elliptically polarized, a simpler way is to stick a λ / 4 phase compensation film 15 on the outside of the outgoing light polarizer 120 of the liquid crystal display, The phase compensation film 15 is an optical film that can provide a phase compensation function, and the range of the wavelength λ is usually in the visible light range, that is, the wavelength λ is between 380-760 nm. The compensation film 15 has a phase compensation value of π / 2, that is, a retardation thickness of 140 nm, and is adhered to the outgoing light polarizer 120 by an adhesive 13 . A protective film 17 is attached to the compensation film 15 . The compensation film 15 is directly adhered to the outgoing light polarizer 120 without any additional components, so that the outgoing light of the liquid crystal display device can be linearly polarized or elliptically...

Abstract

The invention provides an optical composite film which is used for liquid crystal display devices and arranged at one side of outlet light of a liquid crystal layer; the optical composite film, in the light outlet direction of the liquid crystal display, sequentially comprises a first polarization layer and a phase compensation layer and can realize the functions of light polarization and phase compensation at the same time, thus changing the outlet light of the liquid crystal display device into the round polarized light or elliptic polarized light, thereby being beneficial to the visible fatigue of the viewers.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to an optical composite film for changing the polarization state of outgoing light. 【Background technique】 [0002] With the continuous development of liquid crystal technology, liquid crystal displays have been widely used. Since the appearance of liquid crystal watches, liquid crystals have attracted attention as an important role in the electronic age. Portable phones, game consoles, electronic dictionaries, video cameras, digital cameras, videophones, and even notebook computers, monitors, and LCD TVs with liquid crystal displays have appeared one after another. Especially recently, in the field of TV and personal computer, liquid crystal display has gradually replaced CRT and become the mainstream of the market. [0003] With the development of informatization, people's demand for information acquisition is becoming stronger and stronger. They need to use personal computers...
