PROBLEM TO BE SOLVED: To provide a light source device which can emit light flat with uniform brightness distribution even with the use of a point light source like a light-emitting diode. SOLUTION: A bundled fiber light guide body 44 is arranged at an incident face 46 side of a sheet light guide plate 45. The light guide body 44 is made a square stick fixed with a fixing member 53 made of a resin in a condition of arranging each plurality of first and second optical fibers 51, and 52 uniformly in the longitudinal direction of the incident face 46 of the sheet light guide plate 45 which opposes each of their light-emitting side end surfaces. Two light-emitting diodes 42, and 43 are arranged at both end surface sides of the light guide body 44. |
