1. A display device comprising:
a substrate;
a semiconductor disposed above the substrate;
a first scanning line;
a second scanning line adjacent to the first scanning line;
a connection electrode electrically connected to the semiconductor;
an inorganic insulating layer covering the connection electrode;
a first projection located just above the first scanning line and disposed on the inorganic insulating layer;
a second projection located just above the second scanning line and disposed on the inorganic insulating layer;
a third projection located just above the second scanning line, disposed on the inorganic insulating layer, and separated from the second projection;
a first color filter disposed on the inorganic insulating layer between the first projection and the second projection;
a second color filter contacting the third projection, disposed on the inorganic insulating layer, and separated from the first color filter;
an organic insulating layer covering the first projection, the second projection, the third projection, the first color filter and the second color filter;
a pixel electrode disposed above the organic insulating layer and electrically connected to the connection electrode; and
a common electrode opposed to the pixel electrode, wherein
the organic insulating layer contacts the inorganic insulating layer between the second projection and the third projection,
a width of the first projection is smaller than a width of the first scanning line, and
a width of the second projection is smaller than a width of the second scanning line.
