Abstract

The invention provides a thin plane light source device that emits high intensity light without deviation and a high quality display device. The plane light source device consists of light guide board 3 that lets the side incident light emit upwardly, and substrate 11 that is installed opposite to the side plane 3a of the light guide board 3. Light source 10a of the first row and light source 10b of the second row are parallel installed on the substrate 11 along the long side 3c of the side plane 3a. Light source 10a and light source 10b are tilted installed opposite to the long side of the light guide board 3. Light source 10b of the second row is set up among the light source 10a of the first row.
