Abstract: A liquid crystal display device includes a first substrate having a first electrode, a second substrate having a second electrode, a liquid crystal layer, a first polarizer, and a second polarizer. A chiral agent is added in a liquid crystal filled in the liquid crystal layer, a pitch of the liquid crystal is about 8-60 μm; an effective optical path difference of the liquid crystal is about 300-550 nm. By adding a chiral agent to the liquid crystal, changing the angle between the stem electrode and the branch electrode or the angle between the polarization axis of the polarizer and the stem electrode, the transmittance is maximized, thereby achieving high transmittance display.

Abstract: A method for manufacturing a light guide plate (LGP) positioning block thereof includes providing a positioning block body of a LGP positioning block and filling and sealing a liquid in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.
