A liquid crystal display device includes a first substrate, a second substrate disposed opposite to the first substrate, a gate line disposed on the second substrate, an electrode layer disposed on the second substrate, and a light shielding portion disposed at a side of the first substrate facing the second substrate. The electrode layer includes a first electrode portion and a second electrode portion. The gate line is disposed between the first electrode portion and the second electrode portion. A projection area of the light shielding portion projected on the second substrate is overlapped with the gate line, and the projection area has a first side and a second side. The first electrode portion has a third side and a fourth side. The third side is disposed away from the gate line, and the first side is disposed between the third side and the fourth side.
