Title:
LIQUID CRYSTAL DISPLAY DEVICE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JPH09230376
Kind Code:
A
Abstract:

To provide a liquid crystal display substrate which is unsusceptible to disconnection of the drain signal line by forming a breaking opposing layer separately from the gate signal line, exposing at least the central portion exclusive of the peripheral portion from the opening section formed in the insulation film and forming a layer superposed with the drain signal line.

The breaking opposing layer 5 is slightly separated from the gate signal line 2. In the region surrounded by the gate signal line 2 and the layer 5, a pixel electrode 4 composed from an ITO film is formed. Then whole area of the surface thus processed is formed with an insulation film consisting of silicon nitride; the insulation film is installed with an opening section 70A which exposes the central section exclusive of the peripheral section of the pixel electrode 4 and an opening section 70B which exposes the central section exclusive of the peripheral section of the layer 5. In addition, in the crossing region of the thin film transistor TFT forming region superposed on a part of the gate signal line 2 on the insulation film and the drain signal line 3, a successively laminated body with a-Si films is formed.
