Abstract
A liquid crystal (LC) display device includes a first substrate having a pixel unit and a second substrate. The pixel unit has a pixel electrode unit including a primary electrode region. A LC layer with chiral dopants is disposed between the first and second substrates. The pixel unit has a first boundary along a horizontal direction of an upper portion of the pixel unit. The first boundary has a first central point. The primary electrode region has a first side along the horizontal direction of an upper portion of the primary electrode region. The first side has a second central point left to the first central point. The primary electrode region has a second side located on the left to the second central point, and a first angle between the first and second sides is larger than 90 degrees or equal to 90 degrees.
