Abstract:
A display device, in which self-luminous elements are arranged, prevents a leakage current through a common layer, provided for the self-luminous elements and disposed throughout its image display area, from causing adjacent pixels to emit unintended light. A light-emitting element layer 102 includes a lower layer 102d and a light-emitting layer. The lower layer 102d has carrier mobility and includes a carrier transport layer or a carrier injection layer. The lower layer 102d is stacked on lower electrodes 100 and banks 106. The light-emitting layer is stacked on the lower layer 102d. An upper electrode 62 is disposed on the light-emitting element layer 102 and supplies carriers to the light-emitting element layer 102 together with each lower electrode. A lower layer 102d has a dividing area 112 on the bank. The dividing area 112 prevents carriers from traveling between adjacent pixels through the lower layer 102d.
