Abstract

The invention pertains to an adhesive sheet that has a gas barrier layer and adhesive layer on at least one side of a substrate, wherein the gas barrier layer is configured from material containing at least oxygen atoms and silicon atoms; with respect to the total amount of oxygen atoms, nitrogen atoms and silicon atoms present in the surface layer of the gas barrier layer, the proportion of oxygen atoms present is 60-75%, the proportion of nitrogen atoms present is 0-10%, and the proportion of silicon atoms present is 25-35%; and the film density in the surface layer of the gas barrier layer is 2.4-4.0 g / cm3. The invention also pertains to electronic devices provided with said adhesive sheet as an electronic device component. The invention provides adhesive sheets of superior gas barrier properties, resistance to folding, and transparency, as well as electronic devices provided with said adhesive sheet as an electronic device component.

Description

technical field [0001] The present invention relates to an adhesive sheet and an electronic device including the adhesive sheet as a member for electronic devices. Background technique [0002] In recent years, organic electronics has attracted attention as a technology that can form displays, circuits, batteries, etc. on flexible plastic substrates at low temperatures close to room temperature using coating or printing processes, and various organic devices are being developed research and develop. [0003] For example, organic EL elements capable of high-intensity light emission driven by low-voltage direct current have attracted attention as light-emitting elements used in liquid crystal displays or electroluminescence (EL) displays. In these displays, in order to realize thinning, weight reduction, flexibility, etc., studies have been made on using a transparent plastic film as a substrate having electrodes. [0004] However, after the organic EL element is driven for ...
