The display device 12 must be accurately matched between the spectroscopic device 11 and the display panel 12 in order to avoid the occurrence of crosstalk in which the left image enters the right eye of the viewer and the right image enters the viewer's left eye. However, at the time of assembly, an assembly error between the spectroscopic device 11 and the display panel 12 can not be avoided, and the spectroscopic device 11 can not be brought into close contact with the display panel 12 exactly according to the design demand, The stereoscopic display effect is not good and even the requirement for stereoscopic image formation can not be satisfied.
