Embodiment Construction

[0029] Referring to Fig. 2 to Fig. 4, in the liquid crystal display device with changing polarization state according to Embodiment 1 of the present invention, a λ / 4 compensation film 16 is pasted on the outgoing light polarizer 110, and the compensation film 16 is an optical film, which can provide As mentioned in the function of wavelength phase delay, the range of wavelength λ is between 380nm and 760nm. The compensation film 16 has a thickness of 140 nm, and is adhered to the outgoing light polarizer 110 by an adhesive 14 . A protective film 18 is attached to the compensation film 16 . The use of the compensation film 16 structure can reduce light loss, and it is directly adhered to the outgoing light polarizer 110 without other additional components, and the cost is low.

[0030] The absorption axis of the polarized light emitted from the outgoing light polarizer 110 is at an angle of 45 degrees to the retardation axis of the compensation film 16. Because the wavelength ...

Abstract

The invention provides a LCD, arranging a light transmitting part in any region in an outer space outside an outgoing light polarizer to change the linear polarized light emitted from the outgoing light polarizer through the light transmitting part into circular or elliptical polarized light before entering into the outer space again. And the invention provides a LCD changing the state of polarized light of the outgoing light and beneficial to reduce visual fatigue of viewers.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device 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 com...
