Abstract

The present invention relates to a resistive touch display panel having anti-scrape layer, which comprises a display apparatus, a first transparent substrate, an adhesive layer, a second transparent substrate, and an anti-scrape layer. The first transparent substrate is disposed on the display apparatus. The adhesive layer is disposed on the first transparent substrate and has an outer periphery. The second transparent substrate is disposed on the adhesive layer. An outer edge of the anti-scrape layer is disposed on the second transparent substrate opposite to the outer periphery. Besides, the outer edge is located inside the outer periphery. Thereby, the internal structure is free from scrapes; the touch sensitivity at the periphery of the touch display panel is improved. Accordingly, superior convenience in usage and practicability can be achieved.

Claims

1. A resistive touch display panel having anti-scrape layer, comprising:

a display apparatus;

a first transparent substrate, disposed on said display apparatus;

an adhesive layer, disposed on said first transparent substrate, and having an outer periphery;
