Abstract

PURPOSE:To display properly a picture even when one connection in a matrix- type picture display panel is disconnected by connecting respective gate and data lines to a drive device at two locations or more with respect to at least either of the gate or data line. CONSTITUTION:A liquid crystal image display panel 11 is driven by the array of a thin film transistor 12. A gate drive device 14 is connected to gate lines G1- Gn at nodes a1'-an' at both sides of the gate line, while a data drive device 15 is connected to data lines D1-Dn at nodes b1-bn and b1'-bn' at both sides of the data line. As a result, even if the gate line G1 is disconnected at one location on the panel 11, or the data line D1 is disconnected at one location, the occurrence of defects on a display screen can be prevented. A picture display panel 16 can be connected to the devices 14 and 15 with use of an extension boards 17 and 18, and the proper display can be carried out.

When displaying an image in the TPT type liquid crystal display device shown in FIG. 5, by applying signals as shown in FIG. 6 (&) (b) to the gate line and the data line, Time-division sampling is performed according to the pixels and the pixels are driven point-sequentially. Conventionally, the image display channel 1, the dart drive device 4, and the data drive device 5 are connected to the dart line G.
They were connected at connection points a1...an on one side of the data lines D1...Dn and connection points S,...bn on one side of the data lines D1...Dn. As the image display channel becomes larger in area and density increases, it is an unavoidable problem that the r-t line or data line will be disconnected within the armpit channel, and in the conventional example shown in FIG. If a gate line or data line breaks in the image display i4 channel, it will appear as a line defect on the display screen. This significantly deteriorates display quality.
