Color display device

A display device comprising:

• a substrate;
• at least one active layer formed on the substrate;
• a first interlayer insulating film formed on the substrate in areas of the substrate where there is no active layer;
• a source electrode formed over a source region of the active layer;
• a drain electrode formed over a drain region of the active layer;
• a gate electrode formed over a date region of the active layer;
• a second inter-layer insulating film formed on the first interlayer insulating film and extending over the source electrode and above the gate electrode;
• a color filter formed over the second interlayer insulating film;
• a transparent-planarizing layer formed over the color filter;
• a pixel electrode formed over the planarizing layer;
• and further comprising a single mask layer formed over the second interlayer insulating film above the gate electrode beneath the planarizing layer extending from a location at least adjacent to the drain electrode.
