Abstract: A touch sensor includes a base, first sensing electrode columns (FSECs), and second sensing electrode columns (SSECs). The base includes a sensing region (SR) including a rounded corner (RC), and a non-SR outside the SR. The FSECs extend in a direction on the base, each FSEC among the FSECs including first sensing electrodes (FSEs), each FSE among the FSEs including sub-electrodes. The SSECs are alternately disposed with the FSECs on the base, each SSEC among the SSECs including second sensing electrodes (SSEs). Sub-electrodes of one of adjacent FSEs among the FSEs are electrically connected to respective sub-electrodes of another of the adjacent FSEs. A sub-electrode closest to the RC among the sub-electrodes includes a rounded edge (RE) corresponding to the RC. A SSE closest to the RC among the SSEs includes a RE corresponding to the RC, and a protrusion part protruding toward the sub-electrode including the RE.

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.
