Abstract: The substrate of a liquid crystal display has a non-square rectangular shape and is bent such that the longer edges of the rectangular shape are nonlinear while the shorter edges are linear. Liquid crystal containerizing micro-cavities of the display are organized to be elongated in the extending direction of the nonlinear longer edges of the substrate while gate lines and liquid crystal injection holes forming areas are formed extending in the extending direction of the linear shorter edges of the substrate. Concentration of mechanical stresses may be reduced due to this configuration.
