Display device and method for manufacturing the same

A display device, comprising:

• a first inorganic insulating layer covering a display region;
• a first organic insulating layer on the first inorganic insulating layer;
• a second organic insulating layer covering the first organic insulating layer;
• and
• a second inorganic insulating layer covering the second organic insulating layer, the second inorganic insulating layer including a region in contact with the first inorganic insulating layer,
• wherein
• an end of the first organic insulating layer and an end of the second organic insulating layer each have a tapering shape,
• the first organic insulating layer has a first side surface located at the end of the first organic insulating layer and a first bottom surface in direct contact with a layer below the first organic insulating layer,
• the second organic insulating layer has a second side surface located at the end of the second organic insulating layer and a second bottom surface in direct contact with a layer below the second organic insulating layer, and
• an angle between the second side surface and the second bottom surface is smaller than an angle between the first side surface and the first bottom surface.
