Abstract: A display device includes a first display panel, a second display panel, and an optical member. The first display panel includes a first substrate and a first cover member on the first substrate. The second display panel is coupled to a first side of the first display panel, and includes a second substrate and a second cover member on the second substrate. The optical member is in a groove defined by the first and second cover members at a boundary of the first and second display panels.

Abstract: A method of predicting a lifetime of a display device according to an embodiment includes creating a machine learning model based on prior degradation rate data according to a degradation time for each of pixels, measuring a first degradation rate data for each of the pixels by inputting a voltage to each of the pixels, predicting a second degradation rate data for each of the pixels using the machine learning model, and estimating a degradation rate for each of the pixels according to a degradation time based on the first degradation rate data and the second degradation rate data.
