Abstract: A display device comprising a first substrate and a second substrate opposing one another, a thin film transistor and a color filter disposed on the first substrate, a planarization layer disposed on the thin film transistor and the color filter and a light blocking portion disposed on the planarization layer, the light blocking portion defining a pixel area, wherein the planarization layer comprises a first protrusion and a second protrusion, wherein the first protrusion is disposed in an area in which the light blocking portion is disposed, wherein the second protrusion is spaced apart from the first second protrusion, and wherein the light blocking portion comprises a first light blocking pattern disposed on the first protrusion, and the first light blocking pattern contacts the second substrate.

Abstract: A display device includes: a first substrate; a gate line on the first substrate, where the gate line extends in a first direction; a data line on the first substrate, where the data line extends in a second direction which intersects the first direction; a thin film transistor connected to the gate line and the data line; a passivation layer on the gate line, the data line and the thin film transistor, where the passivation layer includes a recessed portion; a light blocking portion on the recessed portion of the passivation layer; a main column spacer which protrudes upwardly from the light blocking portion; and a sub-column spacer which protrudes upwardly from the light blocking portion, where the sub-column spacer is spaced apart from the main column spacer.
