ELECTRON EMITTING ELEMENT ARRAY, IMAGE PICKUP DEVICE, AND METHOD FOR MANUFACTURING ELECTRON EMITTING ELEMENT ARRAY

摘要

The present invention addresses the problem of providing an electron emitting element array or the like whereby film peeling of a semiconductor layer and reduction of a current path due to a step between a lower electrode layer and base portions of insulating barrier ribs can be eliminated. An electron emitting element array (1) of the present invention is provided with a semiconductor layer (3) between a lower electrode layer (2) and an upper electrode layer (5), and is characterized in that the semiconductor layer (3) has a first semiconductor layer (21) on the lower electrode layer (2) side, and a second semiconductor layer (22) on the upper electrode layer (5) side.
