Abstract

A 3D image display apparatus includes a display unit, a first polarizer with a polarization axis, a second polarizer and a switching unit. The switching unit includes a first substrate, a second substrate and a liquid crystal layer. The first substrate is disposed with a first conductive layer on an inner surface thereof along a first direction and is electrically coupled to a first voltage source. The second substrate is parallel to the first substrate and disposed with a second conductive layer on an inner surface thereof along a second direction and is electrically coupled to a second voltage source. The first and second directions have an angle therebetween. The liquid crystal layer is disposed between the first and second substrates and includes a plurality of liquid crystals each having a slow axis.

First claim

What is claimed is:

1. A three-dimensional (3D) image display apparatus, comprising:
a display unit;
a first polarizer having a polarization axis;
a second polarizer, wherein the first and second polarizers are disposed on two opposite sides of the display unit, respectively; and
a switching unit, wherein the switching unit and the display unit are disposed on two opposite sides of the first polarizer, respectively, and the switching unit comprises:
a first substrate dispos…
