Abstract

Perfections introduced into a cathode ray tube including a face plate or substantially rectangular face having a pair of mutually opposite curved sides, a screen of cathode luminescence lines disposed on said face plate, and a slotted slotted mask mounted within said tube in separation relation with respect to said screen, the slits being arranged in substantially vertical columns; characterized in that the outline or profile of said vertical columns is related to the profiles or surface contours of said front plate and said mask, with the edge profile of said curved sides of said front plate and with the deflection angle of said tube, and the cathodic luminescence lines of said screen, adjacent said curved sides of said front plate, are parallel to the contour thereof.
