The present invention related to an immersive light-guiding displaying device for cars. The device has a LCD module and a front cover which are bonded together by an adhesion layer. The short side of the LCD module are bonded with a light-guiding rod by a first adhesive element. The back of the front cover are bonded with a diffusion film by a second adhesive element and the diffusion film corresponds to the light-guiding rod. Near the light-guiding rod at least a light source was disposed. The light-guiding rod would guide the light from the light source toward the diffusion film at different directions to illuminate the area corresponding to the diffusion film of the front cover. So the luminance segmental difference on the front cover which was caused by the null zone of the short side of the LCD module would be eliminated to improve the displaying quality of the automobile LCD.
