The cost of a light-emitting element matrix array is reduced by implementing a function equivalent to a light- emitting thyristor by elements different therefrom. A plurality of combinational element are arrayed in one line. The plurality of combinational elements are divided into groups n by n. The bases of transistors included in each group are separately connected to base-selecting lines and the anodes of light-emitting diodes included in each group are commonly connected to one anode terminal every group.

L'invention concerne une matrice d'éléments électroluminescents dont le coût de fabrication est réduit dans la mesure où cette matrice réalise à travers un autre moyen la même fonction qu'un thyristor électroluminescent. Plusieurs éléments combinés chacun constitués d'un transistor et d'une diode électroluminescente sont disposés en ligne de manière à former une matrice. Ces éléments sont divisés en groupes de n éléments. Les bases des transistors de chaque groupe sont reliées à des lignes de sélection de bases, et les anodes des diodes électroluminescentes de chaque groupe sont reliées à une borne d'anode commune.
