The invention discloses a 
light beam imaging device. The 
light beam imaging device comprises a substrate layer, at least one 
light wave generating unit and at least one second graphical layer, whereinthe at least one 
light wave generating unit is arranged above the substrate layer and is in contact with the substrate layer, each 
light wave generating unit comprises a first type of conducting 
layers, a first 
electrode layer and a first graphical layer which are arranged in a laminated manner in sequence, a second type of conducting 
layers and a second 
electrode layer, the graphical layer is used for compounding carriers of the first type of conducting 
layers and carriers of the second type of conducting layers, generating light 
waves and transmitting the light 
waves; the at least one second graphical layer and at least one light wave generating unit are arranged above the substrate layer at an interval, and are in contact with the substrate layer. The 
light beam imaging device providedby the embodiment of the invention can realize multiple functions of generating the light 
waves, transmitting the light waves, modulating the light waves and the like when different 
electrode layersare connected to a power supply; and moreover, the second graphical layer is arranged on the substrate layer, the second graphical layer can be used for transmitting the light waves, when the second graphical layer is directly formed on the substrate layer, the difficulty of film formation is reduced, and the 
transmission loss is reduced.
