Patent number: 9857621Abstract: A liquid crystal display with a high transmittance and a low power consumption rate, includes first and second transmittable substrates, a plurality of gate and data bus lines formed on the first substrate, a plurality of color filters formed on the second substrate, and a plurality of microlenses formed on the first or second substrate corresponding to the gate and data bus lines.

Patent number: 7455940Abstract: A method for fabricating a color filter array substrate includes forming a black matrix on a substrate, depositing a color resist on the substrate and the black matrix, and patterning the color resist to form a color filter layer. The color resist has a boiling point in a range of about 70 to 80 degrees Celsius and has a viscosity in a range of about 3 to 5 centipoise and has a solid particle content below or equal to about 20 percent.Type: GrantFiled: November 12, 2004Date of Patent: November 25, 2008Assignee: LG Display Co., Ltd.Inventors: Chong Chan Eun, Dong Hyo Gu, Jung Young Yu

Patent number: 7277142Abstract: A method of fabricating a color filter substrate of an LCD is disclosed. By forming the color filter layer from a hydrophobic material, a fluid black matrix material deposited on the surface of the substrate including the color filter layer flows from the surface of the color filter layer and accumulates between sub-color filters of the color filter layer. The black matrix material is then hardened, permitting the black matrix to be formed between the sub-color filters but not on the color filter layer. Accordingly, the number of mask processes for forming a black matrix is reduced. Further, since the black matrix is only disposed between the sub-color filters, an overcoat layer to eliminate the step difference due to the color filters need not be formed.Type: GrantFiled: October 19, 2004Date of Patent: October 2, 2007Assignee: LG Philips LCD Co., Ltd.Inventors: Dong-Hoon Lee, Dong-Hyo Gu

Patent number: 5844644Abstract: A liquid crystal display with in-plane switching mode for improving its light transmittance, includes a first substrate that forms light transmissive portions and light untransmissive portions, a second substrate, and liquid crystal injected between the first and second substrates. The second substrate includes a black matrix, a color filter layer, an overcoat layer and an alignment film. The overcoat layer is patterned to form micro-lenses for refracting the incident light to pass through the light transmissive portions without being blocked by the light untransmissive portions. Various patterning methods can be selected to form the micro-lenses.Type: GrantFiled: July 22, 1997Date of Patent: December 1, 1998Assignee: LG Electronics Inc.Inventors: Young-Jin Oh, Jeong-Hyun Kim, Dong-Hyo Gu, Kyoung-Nam Lim
