1. A display apparatus comprising:
a first substrate having a first side surface, a second side surface opposite to the first side surface, a third side surface, and a fourth side surface opposite to the third side surface;
a second substrate arranged to overlap the first substrate and having a first side surface, a second side surface opposite to the first side surface, a third side surface, and a fourth side surface opposite to the third side surface;
a liquid crystal layer including polymer dispersed liquid crystals placed between the first substrate and the second substrate;
a plurality of light-emitting devices arranged to face the first side surface of the second substrate at a light source side;
an air gap disposed between the light-emitting devices and the first side surface of the second substrate at the light source side;
a first reflector arranged to cover both the second side surface of the first substrate and the second side surface of the second substrate;
a plurality of scanning lines;
a plurality of signal lines crossing the scanning lines;
a thin film transistor disposed at an intersection of one of the scanning lines and one of the signal lines; and
a plurality of pixels arranged in a matrix, the pixels each having a pixel electrode that has a shape of a square,
wherein
an adhesive layer fixes the first reflector to the second side surface of the first substrate and the second side surface of the second substrate,
the first substrate is larger than the second substrate in a plan view,
the light-emitting devices are located fully within the first substrate in the plan view,
the thin film transistor includes a gate electrode and a semiconductor layer,
the gate electrode has an area greater than an area of the semiconductor layer in such manner that the semiconductor layer does not protrude from the gate electrode in the plan view, and
the light emitting devices, each including a luminous body of a first color, a luminous body of a second color, and a luminous body of a third color, are driven by a field sequential method.
