The light-reflecting pattern is arranged above or below the light transmissive member such that a thickness and/or a concentration of material of the light-reflecting pattern in a first region directly above one of the light sources is greater than the thickness and/or the concentration of material of the light-reflecting pattern in a second region above a portion between adjacent ones of the light sources.
