1. A display device comprising:
- a light-transmitting substrate comprising a substrate that transmits at least a light of a predetermined wavelength, the substrate constituting an outermost surface of the display device;
a conductor pattern that is disposed on the substrate and that generates heat to raise a temperature of the substrate when the conductor pattern is supplied with an electric current; and
a light-emitting element that is disposed on a surface of the substrate on which the conductor pattern is disposed, the light-emitting element being connected to the conductor pattern and emitting light when the light-emitting element is supplied with an electric current via the conductor pattern,wherein;
the conductor pattern is directly disposed on the substrate without any adhesive layer;
the conductor pattern conducts heat generated by the light-emitting element to raise the temperature of the substrate at a position remote from the light-emitting element; and
the light-emitting element has a light-emitting surface, the light-emitting element being disposed such that the light-emitting surface is on a side of the light-emitting element facing the substrate and such that light emitted from the light-emitting surface is transmitted through the substrate and is projected to outside of the substrate.

Abstract
A thin light-transmitting substrate showing high thermal conduction efficiency, and having a function of raising surface temperature thereof is provided.
The light-transmitting substrate of the present invention comprises a substrate that transmits at least a light of a predetermined wavelength, and a conductor pattern that is disposed on the substrate, and generates heat to raise temperature of the surface of the substrate when it is supplied with an electric current. The conductor pattern is directly disposed on the substrate without any adhesive layer.
