Curved display device

A curved display device comprising:

• a display substrate curved along a first direction and comprising a pixel electrode disposed in a pixel area and a second alignment layer disposed on the pixel electrode;
• an opposite substrate coupled to the display substrate, curved along the first direction, and comprising a common electrode generating an electric field in cooperation with the pixel electrode and a first alignment layer disposed on the common electrode, wherein each of the first alignment layer and the second alignment layer is curved along the first direction;
• and
• a liquid crystal layer interposed between the display substrate and the opposite substrate and comprising liquid crystal molecules,
• wherein the first alignment layer comprises different material from the second alignment layer, and the first and second alignment layers align a portion of the liquid crystal molecules at pre-tilt angles, wherein the first alignment layer does not comprise a photoinitiator and the second alignment layer comprises a photoinitiator so as to align liquid crystal molecules at different pre-tilt angles from each other,
• wherein the pixel electrode comprises branch portions extending in a direction inclined with respect to the first direction when viewed in a plan view, the branch portions having 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, inclusive,
• wherein a value obtained by dividing the width of the branch portions by the distance between the branch portions is less than or equal to 0.5,
• wherein first liquid crystal molecules, which are adjacent to the first alignment layer, of the liquid crystal molecules have a first pre-tilt angle, and
• second liquid crystal molecules, which are adjacent to the second alignment layer, of the liquid crystal molecules have a second pre-tilt angle smaller than the first pre-tilt angle.
