Claim 0:
1. A display apparatus comprising:
a first glass plate;
a second glass plate;
a display panel facing the first glass plate;
a frame housing a part of the first glass plate, a part of the second glass plate, and a part of the display panel; and
a light source module housed in the frame and disposed away from the display panel,
wherein the first glass plate has a first surface, a second surface opposite to the first surface, and a first side surface continuously formed from the first surface and the second surface,
light emitted from the light source module is made incident on the first side surface of the first glass plate,
the display panel includes
a first substrate facing the first glass plate,
a second substrate facing the first substrate, and
a liquid crystal layer located between the first substrate and the second substrate,

the liquid crystal layer of the display panel is disposed between the first glass plate and the second glass plate,
the light source module is disposed at a position facing the first side surface of the first glass plate,
the light source module includes a third substrate, and a plurality of LED elements mounted on the third substrate,
the third substrate of the light source module is bonded and fixed to the frame to interpose a first heat dissipation sheet having an electrical insulation property therebetween,
the first heat dissipation sheet has a higher thermal conductivity than each of thermal conductivities of the first glass plate, the first substrate and the second substrate,
the display panel further includes a first electronic component mounted on the first substrate and including a driving circuit configured to drive the liquid crystal layer,
a second heat dissipation sheet having an electrical insulation property is bonded and fixed between the first electronic component and the frame,
the second heat dissipation sheet has a higher thermal conductivity than each of thermal conductivities of the first glass plate, the first substrate and the second substrate,
the first heat dissipation sheet is directly stuck to the frame, and
a metal plate is interposed between the second heat dissipation sheet and the frame.
