Abstract
A circuit board structure for a display device includes a substrate, a bump, a protective layer, and a moisture-resistant layer. The substrate includes a first surface and a second surface opposite to the first surface. The bump is disposed on the first surface of the substrate and includes a first inorganic material. The protective layer is disposed on the first surface of the substrate. The protective layer includes an organic material and a first opening, in which the bump is positioned in the first opening. The moisture-resistant layer entirely covers the protective layer. The moisture-resistant layer includes a second inorganic material and a second opening, in which a portion of the bump is exposed in the second opening.
