Abstract
A display device improves the grounding connection of a polarizer by using a metal bridge that couples the polarizer to a ground of the display device. The display device includes a backlight unit (BLU) for providing light for displaying an image, a plurality of pixels for modulating the light provided by the BLU, a polarizer for filtering the light provided by the BLU, and the metal bridge. The metal bridge is disposed in a non-display area surrounding a display area of the display device.
