Patent number: 8514211Abstract: A display panel includes a power line supplying power, and a plurality of pixels connected with the power line, each pixel including a plurality of sub-pixel regions, and receiving the power to display an image. Each of the pixels further includes a plurality of driving thin film transistors and a plurality of light emitting units. Each of the driving thin film transistors are positioned in respective sub-pixel regions to receive the power to output driving signals. Each of the light emitting units are connected to respective driving thin film transistors, have relatively longer lengths in a first direction, and have the same width in a second direction substantially perpendicular to the first direction. One among the plurality of light emitting units is longer than the remaining light emitting units to thereby improve a light emitting efficiency and image display quality of a display panel.Type: GrantFiled: April 17, 2009Date of Patent: August 20, 2013Assignee: Samsung Display Co., Ltd.Inventors: Min-Hyuk Choi, Chun-Gi You, Jong-Hyun Park, Doo-Hyun Woo, Dong-Ki Lee, Young-Dong Kwon, Jin-Hee Kang
