  • Patent number: 9298054
    Abstract: Disclosed are a liquid crystal display (LCD) device and a method of manufacturing the same, which can increase a transmittance of a high-resolution pixel. The LCD device includes a gate line formed to be shared by vertically adjacent first and second pixels, a data line formed to interest the gate line, first and second thin film transistors (TFTs) respectively formed in the first and second pixels, a passivation layer formed to cover the first and second TFTs, including a contact hole that exposes drains of the first and second TFTs, first and second pixel electrodes formed on the passivation layer and in the contact hole, and respectively connected to the drains of the first and second TFTs, and a common electrode formed under or on the first and second pixel electrodes.
