an array substrate including an insulating basement having a first surface and a second surface opposed to the first surface;

a first organic insulating layer which is located alongside the second surface and which is closely adhered the array substrate; and

a second organic insulating layer closely adhered the first organic insulating layer, the first organic insulating layer being located between the array substrate and the second organic insulating layer,

a plurality of bubbles being mixed in the second organic insulating layer,

the second organic insulating layer having an elastic modulus that is lower than that of the insulating basement.
