Problems solved by technology

However, the distance between the electrode 26 and the touch electrode 52 also decreases (d1→d2) at the same time, so the parasitic capacitance component formed between the electrode 26 and the touch electrode 52 increases (c1→c2)
The parasitic capacitive component (c2) may have an effect on the touch electrodes 52 to reduce the sensing characteristics, thereby reducing the overall sensitivity of the touch panel
[0014] As a result, a distance (d1) higher than a predetermined level should be maintained between the electrodes 26 on the lower substrate 10 and the touch electrodes 52, resulting in limitations in widening the viewing angle of the display device.

Abstract

Provided are an organic light emitting display device and a fabricating method using the same. The organic light emitting display device (100) and a fabrication method comprising a touch electrode layer (150) including touch electrodes (152) and touch lines (155) on an upper substrate (130) which are directly formed on the upper substrate (130) to secure a large distance between the touch electrodes (152) and cathode as well as minimize a distance between the upper and lower substrates (110, 130), thereby widening the viewing angle of an image while reducing a parasitic capacitance.

Description

technical field [0001] The present disclosure relates to an organic light emitting display device, and more particularly, to an organic light emitting display device of an in-cell type touch integrated display device and a manufacturing method thereof. Background technique [0002] Display devices are used in electronic devices and the like. Touch screens have been implemented to enable users to select graphical objects or regions displayed on the touch screen. [0003] The touch screen for the display device can be implemented as an add-on type touch screen in which a touch panel is adhered to the display panel, or an in-cell type touch integrated display device in which touch electrodes and touch sensing lines are formed inside the display panel. . In particular, an in-cell type touch-integrated display device is advantageous due to its improved touch sensitivity and thin nature. [0004] The first substrate has a light-emitting unit, and the second substrate has a colo...
