Display Device and Manufacturing Method Thereof |
摘要 |
A display device in which light leakage in a monitor element portion is prevented without increasing the number of steps and cost is provided. The display device includes a monitor element for suppressing influence on a light-emitting element due to temperature change and change over time and a TFT for driving the monitor element, in which the TFT for driving the monitor element is provided so as not to overlap the monitor element. Furthermore, the display device includes a first light shielding film and a second light shielding film, in which the first light shielding film is provided so as to overlap a first electrode of the monitor element and the second light shielding film is electrically connect to the first light shielding film through a contact hole formed in an interlayer insulating film. The contact hole is formed so as to surround the outer edge of the first electrode of the monitor element. |
