Abstract: A curved display device includes a display substrate, an opposite substrate, and a liquid crystal layer interposed between the display substrate and the opposite substrate. The display substrate is curved along a first direction and includes a pixel electrode and a second alignment layer disposed on the pixel electrode. The opposite substrate is coupled to the display substrate to be curved along the first direction and includes a common electrode and a first alignment layer disposed on the common electrode. The first alignment layer comprises different material from the second alignment layer. The pixel electrode includes branch portions extending in a direction inclined with respect to the first direction when viewed in a plan view, and a pitch, which is defined by a sum of a width of each branch portion and a distance between the branch portions, is within a range from about 7.5 micrometers to about 8.5 micrometers.

Abstract: A display apparatus includes a display panel, a polarizing plate, and a patterned retarder. The display panel includes a first substrate including a signal line and a pixel. A second substrate faces the first substrate. An image display device is disposed between the first and second substrates. The first substrate is disposed in a position to which external light is incident. The polarizing plate is disposed above the first substrate of the display panel. The patterned retarder is disposed between the polarizing plate and the signal line. The patterned retarder retards the external light such that the external light reflected by the signal line does not pass through the polarizing plate.
