摘要： A display panel assembly is provided to produce a display panel assembly having a large size, by disposing a polarization axis changing unit between a lower polarizing plate and a display panel and between an upper polarizing plate and the display panel so that the lower polarizing plate and the upper polarizing plate have the same polarization axis. An upper polarizing plate(100) has a first polarization axis(10). A lower polarizing plate(200) is disposed to face the upper polarizing plate. The lower polarizing plate has a second polarization axis(20) having the same direction as the first polarization axis of the upper polarizing plate. A display panel(300) is disposed between the upper polarizing plate and the lower polarizing plate. The display panel changes the transmittance of light to display an image. A polarization axis changing unit(400) is disposed between the upper polarizing plate and the lower polarizing plate. The polarization axis changing unit rotates the light, which is polarized in a predetermined direction, by 90 degrees with respect to the predetermined direction.

摘要： A liquid crystal device comprises two electrodes 30,40 parallel to each other formed on one 10 of two substrates 10,20, homeotropic alignment films 90 formed on the substrates and a liquid crystal material 70 having positive dielectric anisotropy injected between the substrates. When a voltage V is applied to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the generated electric field is symmetrical with respect to the boundary-plane equidistant from each of the two electrodes, the liquid crystal molecules 80 are symmetrically aligned with respect to the boundary-plane, and the optical characteristic is compensated in both regions divided by the boundary-plane, thereby obtaining a wide viewing angle. The electric field does not exert any influence on the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel to the substrate and perpendicular to the two electrodes; and thus, it is perpendicular to the liquid crystal molecules. The device also comprises means for varying directions of long axes of molecules of the liquid crystal layer, wherein the layer has at least two adjacent regions, the molecules of any one region being aligned in the same direction, and the molecules of two regions are aligned symmetrically with respect to the plane-boundary of the regions. The parallel electrodes in each pixel unit may be bent, and in adjacent pixels may be in different directions.
