Abstract: A free-form display is disclosed which makes a step-like pattern adjacent to a free-form portion less visible. The free-form display has an active area and a bezel area, and at least part of a boundary between the active area and the bezel area has a free-form portion. The free-form portion comprises subpixel electrodes and a light blocking portion. A plurality of subpixel electrodes are placed in areas defined by a plurality of gate lines and a plurality of data lines that intersect each other. A light blocking portion has openings exposing the subpixel electrodes, respectively, and is arranged to overlap the gate lines and the data lines. The active area comprises subpixel areas where the subpixel electrodes are placed, and a non-pixel area where no subpixel electrodes are placed. The openings of the light blocking portion adjacent to the non-pixel area, are made in different sizes.
