Embodiment Construction

[0017] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0018] figure 2 is a cross-sectional view of an organic light emitting display device according to the present invention.

[0019] figure 2 The illustrated organic light emitting display device is provided with an active area AA and a pad area PA.

[0020] In the pad area PA, a plurality of pads 150 are formed to respectively supply driving signals to scan lines, data lines, high voltage (VDD) supply lines, and low voltage (VSS) supply lines 160 located in the active area AA.

[0021] Each pad 150 includes a pad electrode 152 and a pad cover electrode 154 .

[0022] The pad electrode 152 is formed of the same material as the gate electrodes 206 and 106 on the gate insulating pattern 112 having the same shape as the pad electrode 152 .

[0023] The pad cover electrode 154 is conductively connected to the pad electrode...

Abstract

Disclosed are an organic light emitting display device which may implement high resolution and a method of manufacturing the same. The organic light emitting display device comprises a plurality of storage capacitors arranged on the substrate; at least one buffer layer arranged on the storage capacitors; a plurality of transistors overlapping with each storage capacitor on the condition that the at least one buffer layer are inserted between the transistors and the storage capacitor; and the light emitting elements connected with the transistors. According to the present invention, a sufficient process margin may be assured, high resolution may be implemented and yield may be improved.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2016-0143976 filed on October 31, 2016, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The invention relates to an organic light-emitting display device and a manufacturing method thereof. More specifically, the present invention relates to an organic light emitting display device capable of achieving high resolution and a manufacturing method thereof. Background technique [0003] A display device that displays various information on a screen is a core technology in the information communication era, and has been developed to meet the trends of thin profile, light weight, portability, and high performance. Therefore, organic light emitting display devices that control the amount of light emitted from organic light emitting layers and thus display images are now in the spotlight as flat panel displays capable of reducing weight and volume to compen...
