    Abstract: A display apparatus includes a substrate including a display area and a peripheral area disposed outside of the display area, a plurality of wiring lines disposed in the peripheral area, and an interlayer insulating layer covering the plurality of wiring lines. The interlayer insulating layer includes an upper surface having a first concave-convex surface corresponding to the plurality of wiring lines. The display apparatus further includes a first conductive layer disposed on the interlayer insulating layer and including a second upper surface having a second concave-convex surface corresponding to the first concave-convex surface, a planarization layer disposed on the first conductive layer and having a flat upper surface, a second conductive layer disposed on the planarization layer and having a flat upper surface, and a polarization plate disposed on the second conductive layer.

    Abstract: A method of determining whether a display manufacturing facility is abnormal includes a first step of obtaining facility information data of facilities used to manufacture a display panel, a second step of preparing a display module by attaching a printed circuit board and a driving chip to the display panel, a third step of obtaining preliminary inspection data through an on-off test on the display module, a fourth step of associating the facility information data with the preliminary inspection data, establishing a database by repeatedly performing the first step to the fourth step, obtaining real-time inspection data through an on-off test on a display module to be inspected, determining whether the display module to be inspected is normal, and determining a facility causing abnormality of the display module, from the real-time inspection data by using the database, in case that the display module to be inspected is abnormal is determined.
