Light source apparatus and display apparatus having the same

Abstract

The present invention provides a light source apparatus less costly, capable of being reduced in size and thickness and superior in light combining performance and a display apparatus having the light source apparatus. The light source apparatus has a plurality of light sources different in emission wavelength from each other and a prism sheet having a plurality of mutually parallel fine elongated prisms on at least one surface thereof. Lights from the light sources enter the prism sheet through a light entrance surface of the prism sheet at a predetermined angle and output from an exit surface thereof as color-mixed exiting light. A bandpass mirror is disposed between each light source and the prism sheet to transmit light in a wavelength region emitted from the associated light source and to reflect light in the other wavelength regions.
