Abstract:
A liquid crystal display, comprising:a first substrate and a second substrate facing each other;a liquid crystal material layer injected between the first and the second substrate and aligned homeotropically, the liquid crystal material layer consisting essentially of a liquid crystal material;at least two electrodes parallel with each other formed on either the first or the second substrate;polarizing plates attached to surfaces of the first and second substrates, respectively; andalignment films formed on the first and second substrates for aligning liquid crystal molecular axes of the liquid crystal material layer perpendicularly to the substrates,wherein the transmission axes of the polarizing plates are perpendicular to or parallel with each other,wherein the liquid crystal molecules of the liquid crystal material layer have a pre-tilt angle, andwherein the difference is below 30V between a driving voltage applied to the electrodes when the light passing through the liquid crystal material layer and the polarizing plates has the maximum transmittance and a driving voltage applied to the electrode when the light passing through the liquid crystal material layer and the polarizing plates has a minimum transmittance.
