摘要：
A light emitter and method for manufacturing a light emitter. The light emitter includes a first electrode, a charge injection transport layer, a light-emitting layer, and a second electrode that are layered in this order. At least the light-emitting layer is defined by bank. The charge injection transport layer includes a recessed portion having an inner bottom surface in contact with a bottom surface of the light-emitting layer and an inner side surface continuous with the inner bottom surface and in contact at least partly with a side surface of the light-emitting layer. The inner side surface has a lower edge continuous with the inner bottom surface, and an upper edge is aligned with a portion of a bottom periphery of the bank, the portion being in contact with the light-emitting layer or in contact with a bottom surface of the bank.
