Abstract:
1. A method of manufacturing a light emitting device, comprising the steps of: conveying a substrate in a chamber along a first direction so that the substrate passes over a shield having a plurality of openings on an upper portion of the shield, the shield having a width in a second direction orthogonal to the first direction; heating an evaporation material in an evaporation source provided below the shield so that the evaporation material is let out from the plurality of openings of the shield while conveying the substrate over the shield, thereby, forming a light emitting layer containing the evaporation material on the substrate through an evaporation mask disposed between the substrate and the shield; heating the shield during the formation of the light emitting layer; and moving the evaporation source in the second direction during the formation of the light emitting layer, wherein the plurality of openings is arranged along the second direction, and wherein the width of the shield is larger than a width of the substrate.
