To provide a display device, in which the space between a display plate and a circuit substrate is made narrower, by contriving the positional arrangement of a light source with respect to the circuit substrate.

A light source 40 is provided with both leads 41, 42, an accommodating member 43, and a light emitting element 44 accommodated in this accommodation member 43. The lead 41 is extended from a wiring part formed on the back of a circuit substrate 30, and inserted and fixed on a part of the outside wall 43 at an inner end part 41b and positioned in a recessed part 43a. On the other hand, the lead 42 is, similarly, extended from another wiring part formed on the back of the circuit substrate 30, inserted and fixed on another part of the outside wall 43 at an inner end part 42b and positioned in the recessed part 43a. The light emitting element 44 is connected with each inner end of each lead 41, 42 respectively at both connection terminals.
