FIELD: electricity.
SUBSTANCE: unit of light sources includes light-emitting diode board 17 having surface with a number of light-emitting diodes 16 placed on it and elongated reflective plate 30 at surface of the light-emitting diode board 17. The deflection plate 30 consists of a number of reflective parts 31 surrounding light-emitting diodes 16 when viewed from the top and a number of connecting pieces 32 which connect adjoining reflective parts 31 that surround light sources. Each of connecting pieces 32 has width Y2 which is less than the width Y1 of each reflective part surrounding the light-emitting diodes 16 in direction of a shorter side of the reflective plate.
EFFECT: improvement of image intensity and cost reduction for the unit of light sources.
