  • Array substrate for display device and manufacturing method thereof
    Patent number: 10504800
    Abstract: The present disclosure provides an array substrate for a display device and a manufacturing method thereof. A transparent electrode pattern (ITO) may be formed between a source/drain metal pattern and a passivation layer located above the source/drain metal pattern, which are formed in a passivation hole area of a non-active area of the array substrate. Accordingly, it may be possible to prevent display failure caused by a delamination phenomenon or peel-off of a material of the passivation layer due to the lack of adhesion strength between a metal layer and the passivation layer in the passivation hole area.
    Type: Grant
    Filed: August 23, 2018
    Date of Patent: December 10, 2019
    Assignee: LG Display Co., Ltd.
