摘要:
A display apparatus in which a light shielding layer to partition fluorescent layers of a fluorescent screen has protrusions and depressions capable of providing a discontinuous area at least with a resistance greater than a predetermined value, for a metal layer for a metal back layer and a metal layer for a getter layer. The height or thickness of a light shielding layer is defined higher than the total thickness of a fluorescent layer, a metal layer for a metal back layer, and a metal layer for a getter layer. According to the present invention, it is possible to effectively manufacture a display apparatus whose picture quality is not degraded by an internal electric discharge. Thus, the cost of the display apparatus is decreased.
