  • Backlight unit including array of hyperbolically-shaped micro lenses
    Patent number: 9581735
    Abstract: A backlight unit includes a light source and a two-dimensional micro lens array (MLA) sheet including a plurality of lens unit each having a conic lens shape with a cross-section, taken through the lens axis, having a shape defined by the equation: y = x 2 / r 1 + 1 - ( 1 + k ) ? ( 1 / r ) 2 ? x 2 where k is a constant with a value of less than or equal to ?1, and r is the radius of curvature at the peak of the lens unit.

  • Resist stripping solution composition, and method for stripping resist by using same
    Patent number: 9081291
    Abstract: Disclosed is a resist stripping solution composition, which is highly capable of removing a resist pattern and an etching residue after dry etching or wet etching, manifests excellent anticorrosive effects on metal wiring including aluminum and/or copper because a predetermined polyol compound is used, and also can process a number of substrates because a predetermined amide compound is used, thus greatly contributing to reducing the cost. A method of stripping a resist using the resist stripping solution composition is also provided.
