Abstract: A curved display device comprises: a first substrate and a second substrate facing each other and having a curvature; a liquid crystal layer between the first and second substrates; a first polarizing layer between the liquid crystal layer and a first surface of the first substrate that faces the liquid crystal layer, or positioned to face a second surface of the first substrate opposite to the first surface of the first substrate; and a second polarizing layer between the liquid crystal layer and a first surface of the second substrate that faces the liquid crystal layer, or positioned to face a second surface of the second substrate opposite to the first surface of the second substrate; wherein at least one of the first and second polarizing layers is either between the first substrate and the liquid crystal layer or between the second substrate and the liquid crystal layer.

Abstract: A display apparatus includes a first substrate, a second substrate, and a spacer. The first substrate includes pixel areas including first and second pixel areas adjacent to each other and arranged in a matrix form defined by first and second directions substantially perpendicular to each other. The second substrate faces the first substrate. The spacer is disposed on the second substrate to extend toward the first substrate. Each of the pixel areas includes a pixel electrode and a thin film transistor connected to the pixel electrode through a contact hole.

Abstract: A liquid crystal display includes: a signal controller configured to receive an input image signal corresponding to a gray from the outside, and an image signal corrector configured to correct the input image signal. The image signal corrector is configured to shift a first input image signal value corresponding to a black gray by a first value based on a common voltage, is configured to shift a second input image signal value corresponding to a halftone gray by a second value based on the common voltage, and is configured to shift a third input image signal value corresponding to a white gray by a third value based on the common voltage. The first value and the second value are larger than a kickback voltage of each of the black gray and the halftone gray, and the third value is the same as a kickback voltage of the white gray.
