Abstract

PURPOSE: To improve the contrast of the picture, by providing a light blocking film on the photoconductor layer excluding the phosphor regions, said light blocking film consists of glass-paste containing SiC and is printed on said layer.
CONSTITUTION: On the surface of a transparent base plate 1a, which is a inside surface of a surrounding member 1 constructed of two opposed transparent base plates 1a and 1b and a spacer 1c, there are provided successively a transparent electrode 2, a photoconductor layer 3, and a plurality of phosphors 4 arranged in a matrix configuration. Further, a light blocking film 5, consisting of glass-paste containing about 30wt% of SiC of 400W800 mesh, is formed by printing on the region where the phosphors are not formed. This light blocking film 5 prevents crosstalk between the phosphors 4 and improves the resolution of the picture.
