ABSTRACT:
A display device is provided including a display panel for displaying an image and a backlight panel for providing light to the display panel. The backlight panel includes a vacuum chamber including a first substrate, a second substrate, and a sealing member. Cathode electrodes are on a side of the first substrate along a first direction with a gap between each other. Gate electrodes are between the cathode electrodes. Electron emission regions are at either sides of the cathode electrodes facing the gate electrodes. A diffusion electrode is above the cathode electrodes and the gate electrodes. An insulator is between the diffusion electrode and the cathode electrodes and between the diffusion electrode and the gate electrodes. Openings are in the diffusion electrode for exposing the electron emission regions. A light emitting unit is on the second substrate.
