Abstract
Disclosed is a flat panel display device including a first substrate; an electron emitting region formed on the first substrate; a second substrate opposing the first substrate with a predetermined gap therebetween; a vacuum assembly being formed by the first and the second substrates; and a light emitting region including a phosphor layer with a predetermined pattern and emitting light by electrons emitted from the electron emitting region, and an anode formed on one side of the phosphor layer, wherein the projections and depressions are formed on the anode, or on the second substrate.

A flat panel display device comprising:
- a first substrate;
- an electron emitting region formed on the first substrate;
- a second substrate opposing the first substrate with a gap therebetween;
- the first and the second substrates forming a vacuum assembly;
- and
- a light emitting region comprising:
- an anode;
- and a phosphor layer adjacent the anode and defining a phosphor layer pattern;
- wherein at least one of the anode and the second substrate defines a pattern of projections and depressions adjacent the phosphor layers, wherein the pattern of projections and depressions impart a surface roughness (Ra) ranging from about 0.0001 μm to about 0.3 μm.
A flat panel display device comprising:
- a first substrate;
