摘要: A light source module includes a light source, a light guide plate on the light source and including at least one recess portion in an upper surface thereof, and a filter sheet on an upper surface of the light guide plate and having a pattern. The pattern may be configured to partially reflect and partially transmit light emitted from the light source through the light guide plate.
