Mobile device

A mobile device is provided. The mobile device includes a panel assembly, a cover window and an adhesive tape. The panel assembly displays images and the cover window is mounted onto the panel assembly. The cover window protects the panel assembly and detects touches that occur thereon. The adhesive tape forms an open hole at the central portion to separate the cover window and the panel assembly. The adhesive tape adheres the cover window to the edge portion of the panel assembly. The adhesive tape further includes an air path part that provides an air passage for communicating an air chamber with the open hole. The air chamber fills with air. The mobile device can display images without a pooling phenomenon, and reduce the chance of malfunction when the user touches the panel assembly via the cover window.
