Abstract
A flat luminescent lamp and a method for manufacturing the same are disclosed, in which light weight and high luminance can be obtained and discharge efficiency can be maximized. The flat luminescent lamp includes first and second substrates each having a plurality of concave and convex portions on an opposing surface, first and second electrodes alternately formed in the convex portions on the first substrate at constant intervals, a dielectric layer formed on the first substrate including the first and second electrodes, and first and second phosphor layers respectively formed on the dielectric layer and the second substrate. The method for manufacturing a flat luminescent lamp having first and second substrates includes etching the second substrate to form a plurality of concave and convex portions on one side, forming first and second electrodes alternately on the first substrate at constant intervals, etching the first substrate at both sides of the first and second electrodes at a predetermined depth to form a plurality of concave portions in the first substrate, forming a dielectric layer formed on the first substrate including the first and second electrodes, forming first …
