ABSTRACT:
A monolithic semiconductor luminescent display device has p.sup.+ layers disposed in seven rows and five columns on one of the main faces of an n substrate to form discrete luminescent junctions between them, five anodes disposed on the p.sup.+ layers one for each column and provided with light emitting windows above the junctions, and a cathode disposed on the other main face of the substrate. Seven p.sup.+ control bands extend through the substrate along the rows respectively and include current passageways below the junctions. The passageways have cross sectional areas controlled with reverse voltages applied to the p.sup.+ bands through the gate electrodes respectively.
