Abstract:
1. A liquid crystal display device comprising: a lower substrate having an opening region and a non-opening region adjacent to the opening region; a pixel electrode located on the opening region; an upper substrate located apart from the lower substrate and having an opposite surface facing the lower substrate; a plurality of protrusion type light shielding layer patterns located on a portion of the opposite surface corresponding to the non-opening region; an opposite electrode over the upper substrate, being located on the protrusion type light shielding layer patterns to continuously cover at least two of the protrusion type light shielding layer patterns; and an optically compensated bend (OCB) mode liquid crystal layer located between the pixel electrode and the opposite electrode, wherein each of the protrusion type light shielding layer patterns has two substantially symmetrical sides each having a slope that is configured to control the alignment of liquid crystal molecules of the OCB mode liquid crystal layer.
