摘要 |
<p>A resin-type light guide plate composition, a backlight unit including the light guide plate formed using the composition and a liquid crystal display including the backlight unit. The resin-type light guide plate composition includes urethane-(meth)acrylate oligomer prepared by reacting a reaction product of a compound prepared by reacting divalent polyol and divalent isocyanate with (meth)acrylate monomer including hydroxyl group, hydrogen bond type (meth)acrylate including hydroxyl group or carboxyl group, acrylic monomer having a maximum shrinkage rate of 15% or less, represented by the equation (1): Maximum shrinkage rate % = - 2.58 + 3000 * number of meth �¢ acryl functional groups / molecular weight of acrylic monomer , and a photoinitiator .
The composition can be used for a light guide plate formed by a simple curing process and having excellent adhesion with respect to a base film and adopted to an edge-lit, local dimming backlight unit having a reduced shrinkage rate.</p> |
