Abstract
A plasma-discharge light emitting device is provided. The plasma-discharge light emitting device may include: rear and front panels separated from each other in a predetermined interval, wherein at least one discharge cell may be provided between the rear and front panels, and wherein plasma discharge may be generated in the discharge cells; a pair of discharge electrodes provided on at least one of the rear and front panels for each of the discharge cells; a trench provided as a portion of each of the discharge cells between the pair of the discharge electrodes; and electron-emitting material layers provided on both sidewalls of the trench.
Claims6
A flat lamp comprising:
- rear and front substrates separated from each other in a predetermined interval, wherein at least one discharge cell is provided between the rear and front substrates, and wherein plasma discharge is generated in the discharge cells;
- a pair of discharge electrodes on an outer surface of at least one of the rear and front substrates for each of the discharge cells;
- a trench provided as a portion of each of the discharge cells on an inner portion of the rear and front substrates between the pair of the discharge electrodes;
- electron-emitting material layers on both sidewalls of the trench;
- and
- a fluorescent layer on an inner wall of each of the discharge cells,
- wherein the trench is formed in the rear and front substrates between the pair of the discharge electrodes.
