Abstract
A curved display device including a display substrate, an opposite substrate, a liquid crystal layer, a pixel electrode, a common electrode, and a light blocking layer. The display substrate includes pixel areas included in a display area, and is curved along a first direction. The opposite substrate faces the display substrate and is coupled to the display substrate to be curved together with the display substrate. Domains are defined in each pixel area and arranged in a second direction crossing the first direction. Liquid crystal molecules in a first set of two domains, which are sequentially arranged and disposed adjacent to the light blocking layer, are aligned toward a first side of the display area, and liquid crystal molecules in a second set of two domains facing the first set of two domains are aligned toward the second side of the display area.
