PURPOSE:To project quickly an image to be projected, onto a screen without executing a generation of an OHP sheet, etc., by receiving an image signal from the outside, modulating a luminous flux for forming a picture element, based on this image signal, and projecting it onto the screen. CONSTITUTION:Each luminous flux from a luminous flux distribution wave guide device 2 passes through in the direction of an optical waveguide 13 from an optical waveguide 15, but at the time of passing, an intensity of a light beam us varied by a potential difference which is applied between a positive charge terminal 16 and a negative charge terminal 14. To a terminal group consisting of the positive charge terminal 16 and the negative charge terminal 14, each different potential difference is set, and a light beam which is generated by a light source device 1 is distributed to each picture element by the luminous flux distribution wave guide device 2, and led to an optical modulating equipment 3. On the other hand, an image signal which is inputted from an image device of the outside or an image data base, etc. is developed as a sequential data by an input device 6 to a picture element data by an input device 6, and outputted to the optical modulating equipment 3. Said light beam is modulated by an optical modulating equipment 6, focused by a luminous flux collecting and distributing wave guide device 4 and projected to a screen 7.
