Abstract
A laser screen of a cathode-ray tube has a semiconductor member made of a semiconductor material selected from the group consisting of an A.sup.II B.sup.VI compound or a solid solution of an A.sup.II B.sup.VI compound and a pair of mirror layers formed on the opposite sides of said semiconductor member. The material of the semiconductor member is doped with a donor impurity in the form of an element of the VII Group of the Periodic Table. A content of the donor impurity ranges from 3.multidot.10.sup.17 to 5.multidot.10.sup.18 cm.sup.-3, and the resistivity of the semiconductor member is maximum 10.sup.-1 .OMEGA./cm.
Claims18
