Display device having buffer layer

A display device comprising:

• a first substrate including a display part arranged with a plurality of pixels and a terminal part arranged in an outside of the display part, the display part and the terminal part being on a first surface of the first substrate;
• a second substrate facing the first surface and is made of a resin material;
• a first sealing layer arranged between the first substrate and the second substrate;
• a buffer layer covering an outer edge of the first sealing layer;
• an insulating layer between the first sealing layer and the first substrate, wherein the insulating layer extends outward from an outermost edge of the buffer layer toward the terminal part;
• and
• an adhesive layer arranged between the buffer layer and the second substrate, and between the first sealing layer and the second substrate in a cross-sectional view, the adhesive layer extending outside the outermost edge of the buffer layer,
• wherein
• a part of an end part of the first sealing layer is arranged between the display part and the terminal part;
• the part of the end part and an upper surface of the first sealing layer form a first step part;
• the buffer layer is located at the first step part without overlapping with the display part and has a distance from the surface of the second substrate side to the first substrate which decreases as a distance from the display part increases;
• and
• the second substrate is arranged along the upper surface of the first sealing layer and an upper surface of the buffer layer, extends outside the end part of the first sealing layer, is bonded to an upper surface of the buffer layer via the adhesive layer, and is bonded to the insulating layer in a region between the buffer layer and the terminal part via the adhesive layer.
