Photopressure-sensitive adhesive sheet attached to the separation layer

Abstract

The invention relates to a pressure-sensitive adhesive plate (X) which is an optically pressure-sensitive adhesive plate attached to a separating layer consisting of a pressure-sensitive adhesive layer (20) and a separating layer (10) arranged on one side in the direction of the thickness of the pressure-sensitive adhesive layer (20). In the pressure-sensitive adhesive plate (X)f the proportion of the total projected area of ​​impurities is less than or equal to 20% in the projected plane in the projected image, according to a predetermined evaluation method.
