PROBLEM TO BE SOLVED: To provide a light source substrate support member capable of housing a line-shaped LED substrate and improving light extraction efficiency without increasing the number of components.SOLUTION: An LED substrate support member 110 includes a substrate storage part 113 for storing an LED substrate 200, and a heat radiation part integrally formed with the substrate storage part 113 for radiating the heat generated by the LED substrate 200 on a side opposite to the side for storing the LED substrate 200 in the substrate storage part 113. The substrate storage part 113 stores the LED substrate 200, and includes a bottom surface 1134 opposed to the LED substrate 113, a pair of side walls 1135 opposed to substrate side parts 201 on both sides of the LED substrate 200, and an upper surface part 1136 that extends toward an LED 210 side from each of the pair of the side walls 1135. The upper surface part 1136 includes an opening 1131 for exposing the LED 210 arranged in the LED substrate 200. |
