1. A display apparatus comprising:
a light source;
a display unit comprising a light-transmissive portion having a predetermined design shape, the display unit enabling the design shape to be visually recognized when light emitted from the light source is applied from a bottom surface and passes through the light-transmissive portion; and
a light guide that guides the light emitted from the light source to the light-transmissive portion,
the light guide comprising:
a radiating portion opposed to the light-transmissive portion at a position adjacent to a bottom surface of the display unit, the radiating portion applying the light emitted from the light source toward the light-transmissive portion;
a first peripheral wall enclosing a first space between the radiating portion and the light source;
a second peripheral wall enclosing a second space between the radiating portion and the light-transmissive portion;
an upper wall connecting to the second peripheral wall and extending outside the second space; and
an outer peripheral wall connecting to the upper wall and extending toward the bottom surface,

wherein each of the radiating portion, the first peripheral wall, the second peripheral wall, the upper wall, and the outer peripheral wall is integral to the light guide, and
wherein each or all of the first peripheral wall, the second peripheral wall, the upper wall, and the outer peripheral wall are supporting portions that support the radiating portion.
