Claim Text:
1. A three-dimensional image display apparatus comprising: an image output unit that outputs image light that has a particular polarization, the image output unit having: a retaining substrate including a transparent glass; an optical element retained by the retaining substrate; and a resin polarizing plate pasted with a first adhesive layer on a side of the retaining substrate opposite to a side where the optical element is retained; and a retarder that is pasted onto the polarizing plate with a second adhesive layer and has: a transparent resin base; and a plurality of phase retarding parts that are provided on the resin base and output the image light as mutually differently polarized light, the image light having been incident on the plurality of phase retarding parts, wherein the second adhesive layer is harder than the first adhesive layer, and the storage elastic modulus of the first adhesive layer is more than or equal to about 0.3 MPa and less than or equal to about 0.7 MPa, the storage elastic modulus of the second adhesive layer is more than or equal to about 0.7 MPa and less than or equal to about 2.3 GPa, and the storage elastic modulus of the first adhesive layer is less than the storage elastic modulus of the second adhesive layer.
