Problems solved by technology

[0019] However, in the display devices shown in FIG. 8 and FIG. 9, there is a problem that since the capacitor 306 is arranged on the TCP 308, it is difficult to arrange the capacitor on the power supply line and the input signal line of the source side driver and the gate side driver. In this case, it is necessary to package the driving semiconductor chip and the capacitor in one body, which increases the number of manufacturing steps and increases the cost

[0055] FIG. 1 is a schematic configuration diagram showing a first embodiment of a display device of the present invention. This display device includes a liquid crystal panel 101 as a display panel, a plurality of source-side drivers 102 as driving drivers, and a plurality of gate-side drivers 103 .

[0056] The plurality of source side drivers 102 are arranged in a straight line along one side of the liquid crystal panel 101 . The plurality of gate-side drivers 103 are arranged in a straight line along the other side intersecting with one side of the liquid crystal panel 101 .

[0057] The panel-side wiring 110 is provided on the liquid crystal panel 101, and the panel-side wiring 110 is disposed between the adjacent source-side drivers 102, 102 and between the adjacent gate-side drivers 103, 103. At the same time, the signal lines of the adjacent source-side drivers 102 and 102 and the adjacent gate-side drivers 103 and 103 are electrically connected at the same time.

Abstract

The LCD panel 101 of the present invention includes a panel side wiring 110 that electrically connects mutually adjacent source side drivers 102, 102 and a capacitor 106 connected to the panel side wiring 110 . Therefore, by collectively fabricating the capacitor 106 on the LCD panel 101 together with LCD pixels in a step of fabricating the LCD pixels on the LCD panel 101 , it becomes unnecessary to mount the capacitor 106 on the source side driver 102 , and the cost of the source side driver 102 can be reduced.

Description

technical field [0001] The present invention relates to a display device suitable for use in, for example, a liquid crystal panel. Background technique [0002] Generally, when a driving semiconductor chip for writing display data on a liquid crystal panel is mounted on the liquid crystal panel to form a display device, although a known method is to package the semiconductor chip in a tape carrier package (TCP: Tape Carrier Package) The method of mounting the semiconductor chip on the liquid crystal panel in a state such as that, and the method of directly mounting the semiconductor chip on the liquid crystal panel, but for a large panel, the method of mounting it on the liquid crystal panel in a state of being packaged in a TCP or the like is mainly used. [0003] When the semiconductor chip is directly mounted on the liquid crystal panel, although the package cost is not consumed, the wiring of the control signal formed on the liquid crystal panel becomes longer, and the r...
