MANUFACTURING METHOD OF DISPLAY DEVICE AND DISPLAY DEVICE MANUFACTURED BY THE METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18096640 titled 'MANUFACTURING METHOD OF DISPLAY DEVICE AND DISPLAY DEVICE MANUFACTURED BY THE METHOD

Simplified Explanation

The patent application describes a method for manufacturing a display device.

• The method involves using a preliminary display device that includes a display module, an optical layer, protective films, and adhesive layers.
• A mask layer is formed on one of the protective films by using a laser light along a specific processing line.
• The preliminary display device is then cut at the outer periphery of the processing line using another laser light along a different processing line.
• This method allows for precise and efficient manufacturing of display devices.

Original Abstract Submitted

A method for manufacturing a display device includes providing a preliminary display device including a display module, an optical layer disposed on a first surface of the display module, a first protective film disposed on the optical layer, a second protective film disposed on a second surface of the display module, a first adhesive layer disposed between the optical layer and the first protective film, and a second adhesive layer disposed between the second protective film and the display module, forming a mask layer on the first protective film by irradiating a first laser light on the first protective film along a first processing line, and cutting the preliminary display device at an outer periphery of the second processing line by irradiating a second laser light on the first protective film along a second processing line positioned at an outer periphery of the first processing line.
