Abstract:
The purpose of the present invention is to attain reductions in the number of steps and in necessary members in steps for producing self-luminescent display devices, such as mini/micro light emitting diode (LED) display devices, having an improved antireflection and/or antiglare function and an improved contrast. This optical multilayer product 10 comprises a base 1 and a pressure-sensitive adhesive layer 2 containing a colorant. One surface 1a of the base 1 has undergone an antireflection and/or antiglare treatment 3. The antireflection and/or antiglare treatment 3 is preferably an antiglare layer. In this optical multilayer product 10, the pressure-sensitive adhesive layer 2 has been superposed on the surface 1b of the base 1 that has not undergone the antireflection and/or antiglare treatment.
