Patent number: 8962741Abstract: The present invention provides an overcoat film which has excellent degree of planarization by optimizing the molecular weight of a binder resin included in a thermally curable resin composition for a protective film and the content of each component including the same. In a color filter according to the present invention, it is not necessary to light up all the red, green, and blue (RGB) pixels for eliciting a white light and perform a separate application process of a white portion because an overcoat film according to the present invention may serve as the white portion.Type: GrantFiled: August 12, 2011Date of Patent: February 24, 2015Assignee: LG Chem, Ltd.Inventors: Soon Chun Mok, Seung Hee Lee, Jong Hwi Hwang, Beom Su Park, Sung Hyun Kim, Dae Hyun Kim, Mi Hee Park, U Ra Lee
