Abstract
According to an aspect of the present invention, there is provided a display apparatus including a TFT array substrate on which TFTs are formed in an array, a counter substrate disposed so as to face the TFT array substrate, and a sealing pattern for adhering the TFT array substrate and the counter substrate to each other, wherein the counter substrate comprises a counter electrode, and the TFT array substrate comprises a first conductive layer, a first insulating film formed on the first conductive layer, a second conductive layer disposed so as to intersect the first conductive layer via the first insulating film, a second insulating film formed on the second conductive layer and having at least two layers, and common electrode wiring provided below the sealing pattern and electrically connected to the counter electrode by the sealing pattern, and the sealing pattern overlaps the second conductive layer via the second insulating film.
