Polymer film, and optical member, polarizing member, and display device employing same

An optical member comprising:

• a substrate;
• and
• a low-refractive index layer formed on the substrate,
• wherein the low-refractive index layer comprises;
• a first binder containing a photopolymerized product of a mixture of a side-chain reactive-type photopolymerizable fluoropolymer and a siloxane compound;
• hollow silica particles distributed in the first binder;
• and
• a photopolymerized product of a one-end reactive-type photopolymerizable fluoropolymer, and a modified silicon, which are mainly distributed in a surface side.

A polarizing member comprising:

• a polarizing means polarizing light;
• and
• a low-refractive index layer located on the polarizing means,
• wherein the low-refractive index layer comprises:
• a first binder containing a photopolymerized product of a mixture of a side-chain reactive-type photopolymerizable fluoropolymer and a siloxane compound;
• hollow silica particles distributed in the first binder;
• and
• a photopolymerized product of a one-end reactive-type photopolymerizable fluoropolymer, and a modified silicone, which are mainly distributed in a surface side.

A display device comprising:

• a display means displaying an image;
• and
• a low-refractive index layer located on a surface of the display means,
• wherein the low-refractive index layer comprises:
• a first binder containing a photopolymerized product of a mixture of a side-chain reactive-type photopolymerizable fluoropolymer and a siloxane compound;
• hollow silica particles distributed in the first binder;
• and
• a photopolymerized product of a one-end reactive-type photopolymerizable fluoropolymer and a modified silicone, which are mainly distributed in a surface side.
