Abstract: Discussed is a display device capable of reducing a number of contact holes and thus improving a aperture ratio, in a structure in which a power line is branched so that power is supplied by the branch line to a thin-film transistor. Further, a method for manufacturing the same is discussed. To this end, in the branch line, a contact-hole is not formed adjacent to the driving thin-film transistor, while a contact-hole is formed only adjacent to the power line VDD/Ref. A dual line of the branch line composed of an active layer and a molybdenum-titanium layer extends from the contact-hole to the driving thin-film transistor, so that the power is supplied to the driving thin-film transistor through the molybdenum-titanium layer MoTi.
