COMPOSITION FOR FORMING DOT PATTERN OF LIGHT EMITTING DIODE PACKAGE, BACKLIGHT UNIT COMPRISING THE DOT PATTERN FORMED BY THEREOF AND LIQUID CRYSTAL DISPLAY INCLUDING THE BACKLIGHT UNIT

摘要

PURPOSE: A composition for forming dot patterns of light-emitting diode package, a backlight unit including thereof, and a liquid crystal display equipped with the backlight unit are provided to enhance adhesion with a material of light-emitting diode package and durability. CONSTITUTION: A composition for forming dot patterns of light-emitting diode package comprises urethane-(meth)acrylate oligomer which is manufactured by reacting (meth)acrylate monomer containing hydroxy group with a compound manufactured by reacting divalent polyol with divalent isocyanate, (meth)acrylic monomer which has a maximum shrinkage ratio of 15% or less, and a photo inhibitor. A maximum shrinkage ratio is represented by the following chemical formula 1 : maximum shrinkage ratio (%) = -2.58 + 3000 × number of functional groups of the (meth)acrylic based monomers/ a molecular weight of the (meta) acrylic monomer.
