FIELD: TV equipment. SUBSTANCE: device 10 has screen 22 and in-line electronic projector 26 which generates and controls three aligned electron beams 28 in different paths towards screen. Electron projector has set of cathodes 34 and at least six electrodes 36, 38, 40, 42, 44, 46, which are located on longitudinal axis and spaced from cathodes. First, second and fourth electrodes 36, 38, 42 are made from materials which temperature extension rate is less than temperature extension rate of materials of other electrodes. EFFECT: increased functional capabilities. 8 cl, 14 dwg, 1 tbl
