PURPOSE:To obtain good three dimensional image without complicating the construction, by providing color section means, strive for detecting beam-scanning position and lenticular lens having a definite repeated pitch near the fluorescent screen. CONSTITUTION:The fluorescent screen 1, formed by repeating vertically three primary phosphor strives R, G, B in order, is adhered on the electron gun side of a face plate 2. Black strive is provided between primary colored phosphor strive, and a thin aluminum foil 3 is covered on the electron bun side of the fluorescent screen 1. Further, a color section device, for example an aparture grille 4 having many filament slits to the vertical direction is provided near the fluorescent screen. Lenticular lens 8 having a surface like many pound cakes, which comprise twice holizontally repeated pitch as much as 1 triopitch of phosphor are provided on the front of the face plate 2. Thus, good three dimensional image having simple structure can be obtained. |
