PROBLEM TO BE SOLVED: To enhance the paper whiteness of a screen of a reflection type liquid crystal display device and to improve an image contrast and visibility by providing a diffusion tacky adhesive sheet for liquid crystals having excellent light diffusion performance. SOLUTION: This sheet 39 has a diffusion tacky adhesive layer which is disposed between a light reflection section 32 and a liquid crystal panel 31 to diffuse the light transmitted therethrough. Both sides of the diffusion tacky adhesive layer are provided with release sheets. The diffusion tacky adhesive layer contains tacky adhesives of an acrylic system and fillers. The difference in the refractive index between the tacky adhesives and the fillers is specified to 0.05 to 0.5, by which light is finely diffused and the paper whiteness is improved. |
