Liquid crystal display device and method of fabricating the same

A liquid crystal display (LCD) device, comprising:

• a first substrate and a second substrate facing each other and having a liquid crystal layer interposed therebetween;
• a gate line and a data line crossing each other to define a pixel region on the first substrate;
• a thin film transistor connected to the gate and data lines;
• a first protrusion and a second protrusion formed on the first substrate;
• a pixel electrode connected to the thin film transistor in the pixel region;
• and
• a first patterned spacer and a second patterned spacer formed on the second substrate, wherein the first patterned spacer corresponds to the first protrusion and the second patterned spacer corresponds to the second protrusion,
• wherein the first protrusion has a first height and the second protrusion has a second height such that the first height is greater than the second height,
• wherein the first patterned spacer and the second patterned spacer have substantially a same height, such that the first patterned spacer contacts the first protrusion and the second patterned spacer is separated from the second protrusion,
• wherein the thin film transistor includes a gate electrode extending from the gate line, a gate insulating layer on the gate electrode, a semiconductor layer including an active layer and an ohmic contact layer on the gate insulating layer, and source and drain electrodes spaced apart from each other on the semiconductor layer,
• wherein the first protrusion includes a first layer, a second layer and a third layer such that the first layer is formed of a same layer as the active layer, the second layer is formed of a same layer as the ohmic contact layer, and the third layer is formed of a same layer as the source and drain electrodes,
• wherein the gate line has a first portion with a first width corresponding to the first and second protrusions and a second portion with a second width, the first width being greater than the second width, and wherein the second protrusion includes a single layer of a same layer as the active layer.
