A waveguide device used for a planar display device having an image source for emitting modulated light beams and a display panel for displaying an image. The waveguide device includes a slab waveguide having a light entrance plane and a light exit plane, a lens array comprising a plurality of lenses disposed in the form of a matrix for individually tuning and guiding corresponding modulated light beams to desired positions on the light entrance plane of the slab waveguide, a wedge waveguide for receiving modulated light beams emitted from the light exit plane of the slab waveguide and emitting the received modulated light beams to the display panel to form the image, and a fixing device for fixing the wedge waveguide to the slab waveguide.
