ABSTRACT:
A picture display panel is provided having an envelope with internal reinforcement partitions formed onto a display window. The display window is provided with substantially V-shaped grooves on the outside opposite to contact surfaces with the reinforcement partitions. The reinforcement partitions thus become substantially invisible from the outside. The outermost edges of these V-shaped grooves are preferably rounded, and the picture display window surface between juxtaposed grooves may be convexly curved into cylindrical lenses to make the reinforcement partitions even more invisible.
