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.

Abstract: A curved display device includes a display substrate curved in a first direction and including a plurality of pixel areas, and each of the plurality of pixel areas including a first sub-pixel area and a second sub-pixel area, an opposite substrate facing the display substrate, the opposite substrate coupled to the display substrate and curved in the first direction together with the display substrate, and a liquid crystal layer interposed between the display substrate and the opposite substrate, where first domains are defined in the first sub-pixel area along a second direction crossing the first direction, second domains are defined in the second sub-pixel area along the second direction, and a width in the second direction of each of the first domains is equal to a width in the second direction of each of the second domains.
