摘要： A liquid crystal display includes: a gate line connected to a gate electrode; a semiconductor layer disposed on the gate line and including silicon; an ohmic contact layer disposed on the semiconductor layer; and a data conductor disposed on the ohmic contact layer. The semiconductor layer includes a source region, a drain region, and a channel region disposed between the source region and the drain region. The data conductor includes a data line transmitting a data signal, a source electrode corresponding to the source region, and a drain electrode corresponding to the drain region. A channel step of the semiconductor layer is a height difference between an upper surface in the source region or the drain region and an upper surface in the channel region. The upper surface in the source region or the drain region has a maximum height of the semiconductor layer.
