Abstract: Unevenness in brightness of a plane light source is controlled to improve a display quality of a plane light source. An LED module comprising one or a plurality of light source sections with a high brightness peak value and a large light and dark contrast difference, and an LED module comprising one or a plurality of light source sections with a low brightness peak value and a small light and dark contrast difference, are alternately arranged. The one or the plurality of light source sections comprise a white resist arranged on a substrate region around LED, as a reflection material. The light source section with a large brightness peak value and a large light and dark contrast difference, and the light source with a low brightness peak value and a small light and dark contrast difference, are formed by the difference in a reflection rate of the white resist.
