Description

  The present invention relates to a display device and a liquid crystal display device, and more particularly to a display device and a liquid crystal display device that realizes space saving of a frame portion on which a semiconductor drive element and an FPC cable for connecting an external circuit are mounted.

  With the development of technology in recent years, in a liquid crystal display panel in which a liquid crystal layer is sandwiched and sealed between two glass substrates, the other glass substrate that is outside the display pixel region at the periphery of one glass substrate and that is opposed to the other glass substrate A liquid crystal display device in which a drive element is mounted in a region that is not covered with (hereinafter, this region is referred to as a frame portion) has been put into practical use.

  For example, in the conventional liquid crystal display device described in FIG. 1 of Patent Document 1, at least one semiconductor chip is mounted on at least one frame portion of the liquid crystal display panel, and a plurality of terminal electrodes for connection to the outside are provided. The semiconductor chip and each connection terminal are arranged side by side in the longitudinal direction of the frame portion.

  This conventional liquid crystal display device has two transparent substrates bonded to each other so as to enclose liquid crystal, and the semiconductor chip has a plurality of transparent electrodes for pixels on both transparent substrates for display driving. The driver analog circuit and a logic circuit including a control circuit and / or a memory circuit for the driver analog circuit are formed. A flexible flat cable (FPC cable) is connected to the connection terminal electrode. Furthermore, a large number of pattern wirings for connecting the semiconductor chip and the transparent electrodes for each pixel in both transparent substrates are formed in the frame portion.

  Thus, by arranging the semiconductor chip and each connection terminal electrode in the frame portion in the longitudinal direction of the frame portion, the width dimension in the frame portion can be set to the semiconductor chip and each connection as in the conventional case. The terminal electrode can be made smaller than the case where the terminal electrode is arranged in the width direction of the frame portion.

  However, the liquid crystal display device disclosed in Patent Document 1 has the following problems.

  The first problem is that the cost of the liquid crystal display device becomes high when applied to a liquid crystal panel of VGA or higher. This is due to the high cost of the semiconductor chip. The reason is that when a VGA-compatible signal line driving element is manufactured at a terminal pitch of 50 μm, the length is 96 mm or more, and the yield of the number of semiconductor chips that can be manufactured from one silicon wafer is deteriorated.

  A second problem is that the width of the frame portion becomes wide when applied to a liquid crystal panel of 3 inches or more. This is caused by an increase in wiring space between the semiconductor chip and the liquid crystal panel. The reason is as follows. When the length of the semiconductor chip is 20 mm, the output terminal pitch of the semiconductor chip is 50 μm, the minimum wiring pitch of the liquid crystal panel is 8 μm, and the semiconductor chip is mounted at the center of the frame, the horizontal dimension of the 3-inch liquid crystal panel is 61 mm. Therefore, the dimension in the frame portion length direction from the edge portion of the liquid crystal panel to the edge portion of the semiconductor chip is 20.5 mm. Here, assuming that wiring is performed obliquely from the terminal at the edge of the liquid crystal panel to the terminal at the edge of the semiconductor chip, in order to ensure a minimum wiring pitch of 8 μm, the output terminal pitch of the semiconductor chip is 50 μm. This is because an angle of 9.2 ° or more is required, and the size in the frame width direction from the edge of the liquid crystal panel to the edge of the semiconductor chip is 3.3 mm or more.

  The third problem is that the cost of the liquid crystal display device is increased when the scanning line driving element and the signal line driving element are mounted on the two frame portions, respectively. This is due to the cost of FPC cable components and mounting costs. The reason is that the FPC cable is connected to each drive element mounted on each frame portion.

  In order to solve these problems, a driving element in which a driving circuit is configured by a thin film transistor is formed on a glass substrate having the same size as the vertical dimension and / or horizontal dimension of the display panel, and the frame portion and the signal on which the scanning line driving element is mounted. An external circuit connection terminal is provided at a corner portion sandwiched by the frame portion on which the line drive element is mounted, and wiring is connected from the terminal portion to both the input terminal of the scanning line drive element and the input terminal of the signal line drive element. A liquid crystal display device having a configuration has been proposed.

  For example, in the conventional liquid crystal display device described in FIG. 2 of Patent Document 2, a scanning line driving element in which a scanning line driving circuit is configured by a thin film transistor on a glass substrate, and a signal line driving by a thin film transistor on the glass substrate. A configuration is employed in which the signal line driving element that constitutes the circuit is mounted on the frame portion of the liquid crystal display panel.

  As shown in FIGS. 19 and 20, the liquid crystal display panel of the conventional liquid crystal display device includes a plurality of thin film transistors for applying a voltage to display pixel electrodes, a plurality of scanning lines for selecting the thin film transistors, and the scanning. A glass substrate 1 on the surface of which a plurality of signal lines perpendicular to the lines are formed; a glass substrate 2 on which the counter electrode of the display pixel electrode is formed on the surface and the glass substrate 1 is opposed to the glass substrate 1 with a liquid crystal layer interposed therebetween; A plurality of scanning line electrode arrays arranged on one side of the glass substrate 1 and a plurality of signals arranged on the other side adjacent to the side on which the scanning line electrodes of the glass substrate 1 are arranged. It has a line electrode array.

  Further, the scanning line driving element of this conventional liquid crystal display device is mounted on the frame portion on the scanning line electrode arrangement side of the glass substrate 1 of the liquid crystal display panel, and corresponds to the scanning line electrode arrangement of the glass substrate 1. Further, each output terminal is connected to a corresponding scanning line electrode. Similarly, the signal line driving element of this conventional liquid crystal display device is mounted on a frame portion on the signal line electrode arrangement side of the glass substrate 1 of the liquid crystal display panel, and corresponds to the signal line electrode arrangement of the glass substrate 1. The drive circuit has an output terminal array, and each output terminal is connected to a corresponding signal review electrode.

  In addition, an input terminal derived from the drive circuit is formed at one end edge of the substrate of each drive element, and this input terminal is soldered to a relay wiring for connecting an external circuit wired to the corner portion of the glass substrate 1. Connected by etc. In addition, an external circuit connection terminal electrically connected to the external circuit connection relay wiring is arranged at one end edge of the corner portion of the glass substrate 1.

JP 2002-131772 A (Page 5, FIG. 1) Japanese Patent No. 3033124 (Page 5, Fig. 2)

  However, the liquid crystal display device disclosed in Patent Document 2 has several problems.

  The first problem is that the frame width cannot be reduced. This is caused by the width of the FPC cable for connecting an external circuit. The reason is as follows. With the development of technology in recent years, the width of the drive element has been narrowed to 4 mm or less. The scanning line driving element and the signal line driving element include four power sources and GND, 18 video signals, 10 gradation voltages, 16 control signals, 2 clock signals, and display pixels of the liquid crystal display panel. A power supply is required to supply the counter electrode of the electrode.

Here, assuming that an FPC cable having a wiring width of 40 μm, a wiring pitch of 80 μm, a wiring thickness of 9 μm, and a length of 10 cm is used for external circuit connection, the power supply for the four systems and the power supply for the counter electrode are 50 mA. In order to suppress the voltage drop in the FPC cable to 0.02 V or less when the current flows, the resistivity of the copper wiring is 1.7 × 10 ⁻⁸ [Ω · m]. Wiring is required. Further, assuming that a current of 100 mA flows through the GND, similarly, in order to make the voltage drop in the FPC cable 0.02 V or less, the GND requires 24 or more wires. As a result, since the total number of copper wirings in the FPC cable is 130 or more, the width of the FPC cable is 10.4 mm or more. Therefore, even if the width of the driving element is reduced to 4 mm or less, the width of the FPC cable is larger than this, and the width dimension of the frame portion must be widened in order to connect the FPC cable for external circuit connection.

  The second problem is that the power supply voltage input to the drive element drops. This is due to the wiring impedance from the external circuit connection terminal to the input terminal of the drive element. The reason for this is that, in general, the wiring used on the glass substrate is made of aluminum wiring or chrome wiring, which has a higher resistivity than copper wiring, in order to reduce manufacturing ease and cost. This is because the wiring to the terminal is long and the number of wirings is so large that the wiring width cannot be increased.

  A third problem is that it is difficult to align the terminals when mounting the drive element. This is due to the configuration having the connection terminals on the short side and the long side of the drive element. The reason is that with the development of technology in recent years, the width of the driving element has been narrowed to 4 mm or less, but the input signal pitch of the signal line driving element is 40 or more, so the input terminal pitch is 100 μm or less. . Further, as the resolution of the liquid crystal display panel is increased, the signal line pitch of the liquid crystal display panel is also narrowed. For example, in a 12 inch XGA panel (1024 × 768), the output terminal pitch of the signal line driving element is 80 μm. As described above, both the X direction and the Y direction have a narrow pitch of 100 μm or less, and accurate alignment accuracy is required.

  Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and a first object of the present invention is to save a frame portion of a display panel on which a driver IC and an FPC cable for connecting an external circuit are mounted. An object of the present invention is to provide a display device that realizes space.

  A second object of the present invention is to provide a display device capable of reducing a power supply voltage drop input to a drive element.

  A third object of the present invention is to provide a display device capable of improving productivity.

  A fourth object of the present invention is to provide a display device capable of improving reliability.

(First embodiment)
Referring to FIG. 1, a perspective view of a liquid crystal display device is shown as a first embodiment of the present invention.

  Corresponding to FIG. 19 of the conventional example, the same region as that of the conventional example (FIG. 19) is indicated by the same symbol. 2 is an enlarged plan view of a portion surrounded by a circle A in FIG. 1, FIG. 3 is a cross-sectional view taken along one-dot chain line AA in FIG. 2, and FIG. 4 is a cross-sectional view taken along one-dot chain line AB in FIG.

The glass substrate 2 is formed with a counter electrode 32 of the display pixel electrode formed on the surface.

The scanning line driving element 3 is composed of a polycrystalline silicon thin film transistor on a glass substrate 54 having a length corresponding to the scanning line electrode terminal arrangement length in the longitudinal direction and a width of 4 mm or less, and supplies a voltage to the scanning line.
