Abstract
Provided is a novel light-emitting element. The light-emitting element includes an anode, an EL layer over the anode, and a cathode over the EL layer; a first layer is adjacent to a side surface of the EL layer, and a first portion is adjacent to the side surface of the first layer. The EL layer and the first portion are adjacent to each other with the first layer therebetween. A refractive index of the first portion is lower than a refractive index of the first layer. An angle θ between a bottom surface and the side surface of the EL layer is larger than 90°.
