Abstract

An electronic device includes a stretchable electronic component layer and a decorative component layer. The decorative component layer includes a first sub-layer and a second sub-layer. The first sub-layer is disposed on the stretchable electronic component layer. The second sub-layer is disposed on the first sub-layer. The first sub-layer is located between the second sub-layer and the stretchable electronic component layer. The second sub-layer has a decorative texture. A transmittance of the first sub-layer is less than a transmittance of the second sub-layer.

Claims (45)
