A method for producing a sealing material is provided. The method includes the steps of: molding a resin for forming the sealing material to obtain a resin film; and processing a surface of the resin film to form a bonding surface having an arithmetic average roughness of 10 nm or more and 1,000 nm or less. There is also provided a method for producing a light-emitting device, comprising the steps of: bonding the bonding surface of the sealing material thus produced to a light-emitting element; and bonding a barrier member to a surface of the sealing material on a side opposite to the bonding surface.

A step of forming a layered body including a resin layer (a) containing a resin A having positive intrinsic birefringence and a resin layer (b) containing a resin B having negative intrinsic birefringence, the resin layer (b) being provided on one side of the resin layer (a); a first stretching step of stretching the layered body in one direction at a temperature T1; and a second stretching step of, after the first stretching step, stretching the layered body in another direction that is approximately orthogonal to the previous stretching direction at a temperature T2 which is lower than the temperature T1 to obtain a phase difference plate are performed. By these steps, a phase difference plate wherein a slow axis of the resin layer (a) after the stretching treatment and a slow axis of the resin layer (b) after the stretching treatment are approximately parallel to each other, and in-plane retardation Rea and NZ coefficient NZa in the resin layer (a) after the stretching treatment, and in-plane retardation Reb and NZ coefficient NZb in the resin layer (b) after the stretching treatment satisfy specific relationship is obtained.

The light output surface structure layer has a concavo-convex structure on a surface opposite to the organic EL element. The concavo-convex structure includes flat surface portions parallel to one surface of the organic EL element and an inclined surface portion tilted relative to the flat surface portions. The projected area which is formed by projecting the inclined surface portion in a direction perpendicular to the flat surface portions onto a plane parallel to the flat surface portions is equal to or less than 0.1 times the total area of the flat surface portions. On a cross section of a flat surface portion cut along a plane parallel to the width and thickness directions thereof, the ratio H/W is 1 or greater and 2.5 or less, where H and W are the height and the width thereof, respectively.
