Diffuser film and method of manufacturing the same

A method of manufacturing a diffuser film comprising the steps of:

• providing a transparent substrate;
• forming a colloid layer on said transparent substrate;
• using a mold plate whose surface has a raised texture to roll over said colloid layer to form an indented texture on the surface of said colloid layer;
• and
• solidifying said colloid layer to form a coarse layer.

A diffuser film comprising:

• a transparent substrate;
• a coarse layer with an indented texture located on an upper surface of said transparent substrate;
• and
• a coarse layer with a raised texture located on a lower surface of said transparent substrate.

A method of manufacturing a diffuser film comprising the steps of:

• providing a transparent substrate;
• forming a first colloid layer and a second colloid layer on said transparent substrate;
• using a mold plate whose surface has a raised texture and a mold plate whose surface has an indented texture to roll over said first colloid layer and said second colloid layer to form an indented texture on the surface of said first colloid layer and a raised texture on the surface of said second colloid layer, respectively;
• and
• solidifying said first colloid layer and said second colloid layer to form a coarse layer with an indented texture and a coarse layer with a raised texture, respectively.
