A display device may include a transistor, which includes a first transistor electrode and a second transistor electrode. The display device may further include a pixel electrode, which is electrically connected to the second transistor electrode. The display device may further include a data line, which is electrically connected to the first transistor electrode, wherein the data line includes a bent structure. The display device may further include a light blocking member, which includes a light blocking portion, wherein the light blocking portion extends perpendicular to a section of the data line, and wherein the light blocking portion overlaps both the transistor and the bent structure without overlapping the section of the data line in a direction perpendicular to the light blocking member.
