Abstract
A lighting device includes a light source and a light guide plate including a light source opposed surface through which light from the light source enters and a pair of plate surfaces through one of which the light exits. The light source is opposed to a middle portion of the light source opposed surface with respect to a longitudinal direction thereof. The light source opposed surface has a light entry portion through which the light from the light source enters at a portion opposed to the light source and a non-light entry portion through which the light from the light source does not enter at a portion on either side of the light entry portion. The light guide plate has a shape such that a dimension thereof parallel to the longitudinal direction of the light source opposed surface is decreased as it is farther away from the light source.
