A spread illuminating apparatus having a light conductive plate made of a light transmissible material and a bar-like lamp disposed along and close to an end face of the light conductive plate. The spread illuminating apparatus also having a light reflection pattern having a stair-like configuration from a cross-sectional perspective. The light reflection pattern is formed on a major face of the light conductive plate. The spread illuminating apparatus also has a light dispersive-reflection pattern which has, for example, a plurality of convex surfaces which are formed on a major face of the light conductive plate opposite to the major face of the light conductive plate, which is provided with the light reflection pattern.
