Patent ID: 7341497

Claim:
A method of fabricating a flat-type fluorescent lamp device, comprising: forming a plurality of first electrodes on a first substrate disposed along a first direction, each first electrode having protrusions extending from both sides of the first electrode along the first direction; forming a plurality of second electrodes on the first substrate, the second electrodes each having concave portions that correspond to the protrusions of the first electrode and convex portions that correspond to regions between the protrusions of the first electrode; forming a first fluorescent layer on an entire surface of the first substrate including the first and second electrodes; forming a second fluorescent layer on a second substrate; attaching the first and second substrates together; and wherein the protrusions of the first electrode are symmetrically formed from the both sides of the first electrode, wherein the protrusions of the first electrodes are one of triangular and semicircular shape.
