Problems solved by technology

However, ITO has a low moisture permeability inhibition effect, and ACF 7 has a specific water absorption
In fact, if Figure 12A and Figure 12B As shown, misalignment tends to occur in the case where the metal wiring layer 2 and the TCP wiring 9 are bonded due to variations in alignment accuracy of bonding equipment used in TCP bonding.

Embodiment Construction

[0039] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] An LCD device which is an example of a display device according to a first exemplary embodiment of the present invention will be described below with reference to FIGS. 1 to 5 .

[0041]FIG. 1 is a cross-sectional view showing the structure of a terminal electrode of an LCD device according to this exemplary embodiment. Figure 1A The structure of the LCD device before connecting an external wiring board such as a TCP (Tape Carrier Package) is shown. The TFT substrate 1 as the first substrate is assumed to be an active matrix substrate in which thin film transistors (TFTs) are arranged in a matrix form (not shown) as switching elements. A color filter and a black matrix or the like are formed on the CF substrate 13 as a second substrate. A liquid crystal material 14 is sandwiched between the TFT substrate 1 and the CF substrate 13 and ...

Abstract

A display device includes a first substrate having a group of terminal electrodes on one side thereof, at least one of the terminal electrodes forming a branched electrode with an isolation region extending along an elongating direction of each the terminal electrode and a second substrate opposing the first substrate such that the terminal electrodes are exposed from an overlapping area of the first substrate and the second substrate.

Description

[0001] This application is based on and claims the benefit of priority of Japanese Patent Application No. 2007-225342 filed on August 31, 2007, and Japanese Patent Application No. 2008-162070 filed on June 20, 2008, which The disclosure of is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a display device, in particular, to a display device having terminal electrodes for connection to an external wiring board. Background technique [0003] In recent years, display devices, especially flat panel display devices have been widely used as high-resolution displays. A liquid crystal display (LCD) device is one of these flat panel display devices. This LCD device has a substrate (hereinafter, referred to as TFT substrate) in which switching elements such as thin film transistors (TFTs) are formed, and an opposite substrate (hereinafter referred to as CF substrate) in which color filters and black matrices or the like are...
