| 摘要 |
The present invention relates to a readily bondable polyester film exhibiting enhanced brightness and, more particularly, to a readily bondable optical film having a polyester film as a substrate film, wherein at least one side of the substrate film has a readily bondable layer including a polymer primer and silica nanoparticles. The width of the readily bondable layer is within a range of greater than 50 nm and less than 150 nm. According to the present invention, the readily bondable polyester film minimizes the loss of light, and can exhibit enhanced brightness while preventing a rainbow phenomenon from occurring, thereby having an effect of eliminating color distortion of a display. |
