Film and housing using the film

A housing comprising:

• a substrate;
• and
• a film comprising:
• a base layer, the base layer including a first surface and a second surface opposite to the first surface;
• a first patterned layer, the first patterned layer laminated with the base layer partially over the first surface of the base layer, the first patterned layer being belt-shaped and including a plurality of spaced first strip patterns such that a first interval space is defined between first strip pattern adjacent two first strip pattern;
• and
• a second patterned layer, the second patterned layer laminated with the base layer partially over the second surface of the base layer, the second patterned layer being belt-shaped and including a plurality of spaced second strip patterns corresponding to the first strip patterns;
• wherein in the direction perpendicular to the film, the second strip patterns are partially overlapped with corresponding first strip patterns and the rest of the second strip patterns are partially overlapped with corresponding first interval spaces.

A film comprising:

• a base layer, the base layer including a first surface and a second surface opposite to the first surface;
• a first patterned layer, the first patterned layer formed on the first surface of the base layer and having a plurality of first pattern;
• and
• a second patterned layer, the second patterned layer formed the base layer and having forming a plurality of second pattern;
• wherein the first pattern of the first patterned layer are partially off-set with corresponding second pattern of the second patterned layer.
