Light polarizing sheet and manufacturing method for same

A light polarizing sheet comprising;

• a first polarizing lens sheet including a sheet-shaped substrate and a lens portion formed on one side of the substrate and
• a second polarizing lens sheet including a sheet-shaped substrate and a lens portion formed on one side of the substrate;
• wherein the first polarizing lens sheet is disposed such that the lens portion of the first polarizing lens sheet opposes the other side of the second polarizing lens sheet substrate, and an ionizing radiation curable resin or tacky particles are provided into a gap between the first and the second polarizing lens sheets.

The light polarizing sheet of claim 5, wherein the index of refraction of the ionizing radiation curable resin is set to be not less than 0.05 below the index of refraction of the second polarizing lens sheet.

A light polarizing sheet comprising;

• a polarizing lens sheet including a sheet-shaped substrate and a lens portion formed on one side of the substrate;
• a protruding structure disposed such that one end thereof contacts another side of the substrate and
• a diffusion sheet supported by the other end of the protruding structure so as to oppose the other side of the substrate.

A light polarizing sheet comprising;

• a polarizing lens sheet including a sheet-shaped substrate and a lens portion formed on one side of the substrate and
• a diffusion sheet disposed facing to the other side of the substrate of the polarizing lens sheet;
• whereby the diffusion sheet is disposed apart from the other side of the polarizing lens sheet using a transparent ionizing radiation curable resin portion discretely disposed between the other side of the polarizing lens sheet substrate and the diffusion sheet.

A method for manufacturing a light polarizing sheet comprising steps of

• forming a tacky layer by transparent material on the other side of a first polarizing lens sheet substrate, on the flat portion of a second polarizing lens sheet second lens portion, or on the other side of the first polarizing lens sheet substrate and the flat portion of the second lens portion on the second polarizing lens sheet;
• and adhered the flat portion of the second lens portion of the second polarizing lens sheet to the other side of the substrate of the first polarizing lens sheet.

A method for manufacturing a light polarizing sheet including a polarizing lens sheet having a sheet-shaped substrate and a first lens portion formed on one side of the substrate, a protuberance structure linked at one end to the other side of the substrate, and a diffusion sheet supported on the other end of the protuberance structure and disposed so as to face to the other side of the substrate, the method comprising the steps of

• forming at the other end of the protuberance structure a transparent material tacky layer which retains tackiness after curing and
• pressing the diffusion sheet onto the other end of the protuberance structure and adhering the polarizing lens sheet and the diffusion sheet.

A method for manufacturing a light polarizing sheet including a diffusion sheet and a polarizing lens sheet having a sheet-shaped substrate and a lens portion formed on one side of the substrate, the method comprising steps of;

• coating a transparent material which retains tackiness after curing onto the other side of the substrate of the polarizing lens sheet in a dotted or striped pattern and
• superimposing the other side of the polarizing lens sheet substrate and one side of the diffusion sheet to adhere together the polarizing lens sheet and the diffusion sheet.
