PROBLEM TO BE SOLVED: To provide an element substrate for a display device using a plastic film for the substrate, wherein degradation of display characteristics due to infiltration of water vapor is prevented. SOLUTION: A barrier insulating layer 38, an electrodes 30 where display signals are supplied, and a barrier insulating layer pattern 28 formed between patterns of a plurality of electrodes 30 are successively formed via an adhesive layer 35 on a plastic film 10, and a two-layer barrier layer structure is formed. The element substrate for the display device is applicable to an organic EL display or a liquid crystal display device. COPYRIGHT: (C)2007,JPO&INPIT
