1. A display device comprising:
a first substrate including an organic passivation film, a common electrode formed on the organic passivation film, an insulating film on the common electrode, a pixel electrode on the insulating film, and a thin film transistor having a source electrode which is connected to the pixel electrode at a contact portion; and
a second substrate opposed to the first substrate, and including a black layer and a color filter on the second substrate,
wherein the organic passivation film around the contact portion has an inclined surface that is inclined with respect to the first substrate,
wherein the organic passivation film has a thickness D at a position opposed to the color filter, and
wherein an inclination angle of the inclined surface at a position of a thickness of D/3 is different from an inclination angle of the inclined surface at a position of a thickness of 2D/3.
