Optical laminated body, method of manufacturing the same, and display unit

1. An optical laminated body comprising:

a phase difference layer that has, in a same plane, two or more phase difference regions having different slow axis directions from each other, the phase difference layer having oppositely facing first and second faces;

a polarization plate secured to the first face of the phase difference layer by a bonding layer or an adhesive layer;

a base material with a first face secured to the second face of the phase difference layer by a bonding layer or an adhesive layer in between; and

an antireflection layer or an anti-glare layer directly secured to a second face of the b of the base material.

2. The optical laminated body of claim 1 , wherein the phase difference layer comprises two kinds of phase difference region that are stripe shaped and alternatingly arranged in the plane of the phase difference layer.

3. The optical laminated body of claim 1 , wherein the phase difference layer comprises two phase difference regions that are rectangular in shape and arranged in side-by-side relationship.

4. The optical laminated body of claim 1 , wherein the base material is transparent resin selected from the group consisting of triacetyl cellulose (TAC), cycloolefin polymer (COP), cycloolefin copolymer (COC) and polymethyl methacrylate (PMMA).

5. The optical laminated body of claim 1 , wherein the phase difference layer contains a polymerized polymer liquid crystal material.

6. The optical laminated body of claim 1 , wherein the antiglare layer.
