Abstract:
A display device in which a light shielding film is formed so as not to increase the number of steps and its cost, is provided. The display device of the present invention includes a monitor element for controlling influence on a light-emitting element due to temperature change and change with time and a TFT for driving the monitor element, and the TFT for driving the monitor element is provided so as not to be overlapped with the monitor element. The display device of the present invention includes a first light shielding film provided so as not to be overlapped with a first electrode of the monitor element, and a second light shielding film provided so as to be overlapped with an outer edge portion of the first electrode.
