Abstract:
The invention provides an organic EL display device that, even if bent, is not prone to plastic deformation and has improved moisture blocking characteristics.An organic EL display device includes: a glass substrate; an organic EL layer formed on an upper side of the glass substrate; and a support substrate glued on a lower side of the glass substrate via a first adhesive. Recessed portions or projecting portions are formed on the glass substrate at a side thereof facing the support substrate. The recessed portions or a space between each of the projecting portions is filled with the first adhesive.
