PURPOSE:To obtain a good three-dimensional color image by setting the curvature and the thickness of semicircular lenses installed in response to color fluorescent stripes, to each prescribed value. CONSTITUTION:On the inner surface of the phase plate 2 of a color cathode-ray tube, the first - the third color fluorescent stripes are arranged in the horizontal direction in succession, forming the fluorescent surface 1 having a prescribed curvature. A beam position detecting stripe 7 is arranged in relation to the flourescent surface. Outside the phase plate 2, is arranged is lens sheet 8 constituted of the semicircular lenses each having a prescribed curvature and thickness in correspondence to the integer number of couples of color fluoresecnt stripes constituted of the first - the third color fluorescent stripes. In response to the detection signal formed by the beam scanning position detecting stripe 7, the picture elements having parallax information between the right and the left are formed alternately in the unit of the integer number of couples of color fluorescent stripes. |
