Abstract: Disclosed is a display apparatus and light source device which includes an optical dome having a specifically defined shape to be able to maintain an optical profile of a light source. A display apparatus includes a printed circuit board (PCB); a light emitting diode (LED) chip mounted on the PCB and configured to emit light; an optical dome disposed over and enclosing the LED chip; a liquid crystal panel configured to block or pass light output from the LED chip; and an optical film arranged between the LED chip and the liquid crystal panel, wherein a ratio of a height of the optical dome to a diameter of a bottom surface of the optical dome is 0.25 to 0.31.
