Abstract

A display device that may minimize voltage drop of a power source supplied to a pixel (P) is disclosed. The display device comprises a power generator (220) generating a driving power source (VDD); a display panel (100) that includes a plurality of pixels (P) and displays images by using the driving power source (VDD); and a printed circuit board (500) having a power transfer line (510) for transferring the driving power source (VDD) output from the power generator (220) to the display panel (100), wherein the power transfer line (510) is provided in a closed-loop type.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2013-0162077 filed on December 24, 2013, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a display device, and more particularly, to a display device that can minimize a voltage drop of a power supply supplied to a pixel. Background technique [0003] Recently, with the development of multimedia, the importance of flat panel display devices is increasing. In response to this trend, flat panel display devices such as liquid crystal display devices, plasma display devices, and organic light emitting display devices have been commercialized. Among these flat panel display devices, organic light emitting display devices have received great attention as next-generation flat panel display devices due to their fast response speed based on self-luminescence, low power consumption, and excellent viewing angle characteristics.
