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.

Abstract: Provided is a display device. The display device includes a substrate including an active area in which a plurality of pixels is disposed and a non-active outside a periphery of the active area. A plurality of signal lines is disposed in parallel with one another and extend in a first direction in the non-active area. Each of the plurality of signal lines includes a first portion, a second portion, and a third portion which are sequentially connected to one another. The first and third portions extend in the first direction and are disposed in parallel with one another. Embodiments provided herein facilitate a reduction of electromagnetic interference between the display device and an external electronic device.
