FIELD: electricity.SUBSTANCE: light-source unit includes a light-emitting diode 17 serving as a light source, diffuser lens 19, reflective sheet 23 of the board and a limiter 27. The diffuser lens 19 is faced towards emitting surface 17a of light emitted by the light-emitting diode 17. The reflective sheet 23 of the board is placed so that it is faced towards surface of the diffuser lens 19 which is located closer to the light-emitting diode 17 and configured for the purpose of light reflection. The limiter 27 protrudes from the diffuser lens 19 in direction of reflective sheet 23 of the board and it limits mutual alignment between the diffuser lens 19 and reflective sheet 23 of the board.EFFECT: removing irregularity of the light emitted from the diffuser lens.32 cl, 29 dwg |
