Display device, and method for monitoring contact depth of flexible printed circuit board of same

The invention relates to a display device for monitoring the contact depth of a flexible printed circuit board. The display device includes: a display panel including a pad portion disposed at a non-display area; and a flexible printed circuit board including a contact portion which contacts the pad portion. The flexible printed circuit board includes a scale pattern spaced apart from the contactportion. The scale pattern includes a plurality of scales arranged at a constant interval in a direction parallel to an extending direction of the contact portion. An end portion of the scale patternis aligned with an end portion of the contact portion on an imaginary line. 本公开涉及一种用于监视柔性印刷电路板的接触深度的显示装置，所述显示装置包括：显示面板，所述显示面板包括设置在非显示区域处的焊盘部分；和柔性印刷电路板，所述柔性印刷电路板包括接触所述焊盘部分的接触部分。所述柔性印刷电路板包括与所述接触部分间隔开的刻度图案。所述刻度图案包括在平行于所述接触部分的延伸方向的方向上以恒定间隔排列的多个刻度。所述刻度图案的端部与所述接触部分的端部在假想线上对准。
