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.
