<p>PURPOSE:To provide a large display area in comparison with the area of the base plate by providing a driving circuit on a main surface faced to the main surface of the base plate where the display area is formed. CONSTITUTION:A signal line 21 and a scanning line 31 are arranged in the shape of a matrix on a main surface 13 of an insulated board 11 of a base plate 1 for display device, a thin film transistor 41a is arranged at the intersection part, and a display area 201 is composed of the group of picture element electrodes 51. The signal line 21 and the scanning line 31 are extended through connecting parts 14 and 16 provided on the end face of the insulated board 11 to a main surface 15 faced to the main surface 13. A signal line driving circuit 121 and a scanning line driving circuit 131 are provided on the peripheral part of the main surface 15. Namely, by installing the driving circuits 121 and 131 on the main surface 15 faced to the main surface 13, the area of the base plate 1 for display device can be reduced in comparison with the conventional area, and the base plate 1 with the integrated driving circuits can be provided.</p> |
