Display device

Abstract

The drive substrate and an opposed substrate are joined to each other through a gap in which a liquid crystal is held. Pixels electrodes are provided on the drive substrate in a matrix form and, an opposed electrode is formed on the entire surface of the opposed substrate. The drive substrate 1 has a plurality of thin film transistors each for switching one of the pixel electrodes, a first interlayer insulating film for covering the thin film transistors, interconnect electrodes patterned on the first interlayer insulating film and connected to the thin film transistors, a second interlayer insulating film for covering the interconnect electrodes and a black matrix patterned on the second interlayer insulating film and used for shielding the thin film transistors beneath the second interlayer insulating film. The black matrix is covered by a planerization layer and the pixel electrodes are patterned on the planerization layer. The pixel electrodes are connected to the interconnect electrodes through the black matrix 10 which is made up of a metal film. In a display device of the active matrix type, an on-chip black structure is thus obtained by providing a black matrix also referred to as a light-shielding layer on a drive substrate.
