Abstract:
Provided is a light-emitting module from which light with uniform brightness can be extracted. Further, provided is a beautiful light-emitting module in which Newton's rings are not observed. The light-emitting module includes a first substrate, a light-emitting element formed on one surface side of the first substrate, a second substrate, a conductive spacer maintaining the gap between the first substrate and the second substrate, and a space in which the light-emitting element is sealed between the first substrate and the second substrate. Further, the pressure in the space is lower than or equal to the atmospheric pressure. Furthermore, the conductive spacer is electrically connected to the second electrode in a position overlapping with a partition provided over the first substrate so as to reduce a voltage drop occurring in the second electrode.
