Liquid crystal display device

摘要

A first substrate includes first and second gate lines extending in a first direction, first and second source lines extending in a second direction and a switching element electrically connected with the gate line and the source line. A pixel electrode includes a contact portion contacting with the switching element and extending in the first direction and a main pixel electrode contacting with the contact portion and extending in the second direction. The switching element includes a drain electrode arranged between the source lines. The drain electrode includes a first electrode portion located under the contact portion, a second electrode portion located under the main pixel electrode and connected with the first electrode portion, a third electrode portion connected with the second electrode portion along the first gate line, and a fourth electrode portion connected with the second electrode portion and extending along the second gate line.
