Title:
Display device
Document Type and Number:
Japanese Patent JP6050379
Kind Code:
B2
Abstract:
A liquid crystal panel 11 includes a display area TFT 17, a non-display area TFT 29, and a first interlayer insulator 39. The display area TFT 17 is disposed in a display area AA of an array board 11b. The non-display area TFT 29 is disposed in a non-display area NAA. The non-display area TFT 29 includes a second gate electrode 29a, a second channel 29d, a second source electrode 29b, and a second drain electrode 29c. The second channel 29d is formed from an oxide semiconductor film 36. The second source electrode 29b is connected to the second channel 29d. The second drain electrode 29c is connected to the second channel 29d. The first interlayer insulator 39 is layered at least on the second source electrode 29b and the second drain electrode 29c. The first interlayer insulator 39 has a multilayer structure including a lower first interlayer insulator 39a and an upper first interlayer insulator 39b. The lower first interlayer insulator 39a is disposed in a lower layer and contains at least silicon and oxygen. The upper first interlayer insulator 39b is disposed in an upper layer and contains at least silicon and nitrogen. The upper first interlayer insulator 39b has a thickness in a range from 35 nm to 75 nm.
