PURPOSE: Provided is an exposure device having non-tilt source which can extent a life of light source and secure a light radiation region having high illuminance by radiating the light to panel without a loss of light. CONSTITUTION: The exposure device comprises a fly eye lens(13) having a plurality of spherical lens unit; at least one of light source(10a,10b) which radiates a light to the fly eye lens; elliptic mirrors(11a,11b) which are positioned at the light source so as to collect the light radiated from the light source; a first path controller for controlling a path of the light; a second path controller for controlling a path of the light; and at least one of collimate unit(14b) for controlling a path of the light so as to radiate the light transmitted through the fly eye lens to the panel(20). The elliptic mirrors(11a,11b) are inclined to the second path controller so as to prevent a loss of light radiated to the second path controller. |
