LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD OF THE SAME |
摘要 |
An active matrix substrate or TFT substrate is provided with a lower layer wiring with a groove wiring structure covering surroundings of a copper layer with a barrier metal film is formed by forming a groove at an insulating substrate and depositing the barrier metal film and the copper layer in this groove. This groove wiring structure is used for a TFT substrate of a liquid crystal display (LCD) device. It is possible to manufacture an LCD device with large size, high density, a large aperture ratio and in which the disclination defects originating from a different in level of the lower layer wiring and an occurrence of disconnection failures in an upper layer wiring are suppressed. |
