A light-emitting module 200 illustrated in FIGS. 3A to 3D includes a first substrate 201, a second substrate 202 capable of transmitting an energy ray, a light-emitting element 210 between the first substrate 201 and the second substrate 202, and a sealant 231 which surrounds the light-emitting element 210 and with which the first substrate 201 and the second substrate 202 are attached to each other. The light-emitting element 210 includes a first electrode 211, a second electrode 212, and a layer 213 containing a light-emitting organic compound therebetween. In particular, the first substrate 201 is alternately provided with a high-reflectivity region 205a capable of reflecting part of the energy ray and a low-reflectivity region 205b having lower reflectivity with respect to the energy ray than the high-reflectivity region 205a which overlap with the sealant 231. The sealant 231 includes a low-melting-point glass layer absorbing part of the energy ray.
Components of the light-emitting module in this embodiment will be described below.
<First Substrate and Second Substrate>
The first substrate 201 and the second substrate 202 each have heat resistance high enough to withstand a manufacturing process of the light-emitting module. The first substrate 201 and the second substrate 202 are not particularly limited in thickness and size as long as they can be used in a manufacturing apparatus. Further, the first substrate 201 and the second substrate 202 may have a single-layer structure or a layered structure of two or more layers.
