Abstract: A display device includes an array substrate, an opposite substrate, a printed circuit board, and a conductive member. The array substrate includes pixel electrodes. The opposite substrate faces the array substrate, is coupled with array substrate, and includes a light blocking layer disposed in a non-pixel area of the array substrate. The printed circuit board includes a ground terminal and output terminals to apply a driving signal to the array substrate through the output terminals. The conductive member electrically connects the light blocking layer to the ground terminal.
