Title:
DISPLAY DEVICE AND METHOD FOR MANUFACTURING DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2019124745
Kind Code:
A
Abstract:
To provide a method for manufacturing a display device, by which degradation in position detection accuracy is prevented even when an alignment mark is partially invisible.SOLUTION: A method for manufacturing a display device is provided for forming a plurality of display devices 100 each including a display region, a peripheral region 140 and a boundary region 130 on a first substrate for multi-face patterning. The method includes: forming an identifier 200 on the first substrate for multi-face patterning, the identifier including a first identifying part 210 disposed in the boundary region located at a boundary of the display device and a second identifying part 220 disposed in the peripheral region located between the display region and the boundary region; aligning a laser and the first substrate for multi-face patterning by using the first identifying part; cutting a second substrate for multi-face patterning in the boundary region; aligning a laser and the first substrate for multi-face patterning by using the second identifying part; and cutting the first substrate for multi-face patterning in the boundary region. The step of cutting the second substrate for multi-face patterning includes carbonizing at least a part of the first substrate for multi-face patterning.SELECTED DRAWING: Figure 5
