Abstract:
1. A semiconductor device comprising: a glass substrate; a silicon oxide film on the glass substrate; a thin film transistor including a semiconductor layer comprising crystalline silicon on the silicon oxide film; a gate wiring electrically connected to a gate electrode of the thin film transistor, the gate wiring comprising aluminum; a second wiring intersecting the gate wiring and electrically connected to the thin film transistor; a storage capacitive wiring which extends in parallel with the gate wiring wherein the storage capacitive wiring is formed on a same insulating film as the gate wiring; an organic layer formed over the storage capacitive wiring; and a pixel electrode formed over the organic layer, wherein the storage capacitive wiring has at least first and second portions formed of a same material, the first portion extending under the pixel electrode and having a first width, and the second portion extending across the second wiring and having a second width narrower than the first width, and wherein the same material is selected from the group consisting of tantalum and titanium.
