Abstract

A light-emitting module which efficiently extracts light emitted from a light-emitting element is provided. Alternatively, a light-emitting module having lower power consumption or improved reliability is provided. A light-emitting module includes a window material having a light-transmitting property, a light-emitting element that emits light transmitted from a light-transmitting layer to the window material, and an optical bonding layer between the window material and the light-transmitting layer. The optical bonding layer includes a thick part overlapping the light-emitting element and a thin part surrounding the thick part. The light-transmitting layer, the optical bonding layer, and the window material are provided in decreasing order of refractive index.
