ている。Since an XY matrix type display device can be easily realized using such a thin film EL element, it is used for displays in personal computers and the like. As shown in FIG. 4, this XY matrix type thin film EL display device consists of data side electrodes (D, to D, . . . ) consisting of m transparent electrodes that are orthogonal to each other so as to define mXn pixels. The scanning side electrodes (S, ~S, , ) consisting of the back electrodes of the book are drawn out to both sides or one side of the panel, and one end of the data side electrode connects to the data driver〇〇, ~DD, and one end of the scanning side pole. It has an electrode structure connected to a scan driver SD to SD, and is driven and displayed in a line sequential manner. On the other hand, in addition to such a simple electrode structure, a two-panel electrode structure may be used. In the electrode structure of the two-part panel type, the data side electrodes are divided into upper and lower parts, and a data driver is connected to each of them, so twice the number of electrodes is required compared to the simple electrode structure described above. This two-part electrode structure is suitable for a thin film EL display device with a large display capacity because it has advantages such as doubling the number of lines that can be scanned and reducing power consumption.

支障となる。By the way, the light emitting part of a thin film EL panel is operated by applying a high voltage of about 200V to a very thin film of 1 to 2 microns as shown in Figure 3, so pinholes and various other problems occur in the film. Dielectric breakdown damage is likely to occur due to defects, etc. In particular, matrix type display panels with thin striped electrodes are prone to breakage of electrode lines due to dielectric breakdown damage. In the electrode structure of the matrix type display device described above, the display defect is not limited to the dielectric breakdown damage site, but also causes a line-shaped defect because no light is emitted even beyond the disconnected portion, which poses a practical problem.
本発明の目的は上記！題を解消した薄膜ＥＬ表示装置を
提供することにある。The purpose of the present invention is the above! An object of the present invention is to provide a thin film EL display device that solves the problems.

る。In order to solve the above-mentioned problems, when using the thin film EL display device of the present invention, a two-part display type thin film HL display panel in which a data side electrode is formed which shares the upper half of the display screen and the lower half of the display screen. , a scanning side pole that covers the upper half of the display screen and a scanning side pole that covers the lower half of the display screen, which are provided orthogonally to the data side electrode, are drawn out to both sides of the display screen and share the upper half of the display screen. The electrode structure has an electrode structure in which a scanning side pole that covers the upper half of the display screen and a scanning side pole that covers the lower half of the display screen are connected to form a loop on both sides of the display screen.

２分割型の線順次駆動を行うものである。The data side electrode is divided into two, and scanning side electrodes that share each divided display screen are connected to each other on both sides of the display section,
This forms a loop-shaped scanning pole. i.e. 1
In the thin-film EL display device of the present invention, half the number of scanning-side poles is formed, and two scanning-side poles are simultaneously selected by a scanning driver connected to each loop, resulting in line-sequential drive in a two-part panel type. This is what we do.

期に亘って安定に使用することができる。By connecting the scanning side poles in a loop like this,
Even if a wire breaks due to dielectric breakdown damage, only the damaged part will not emit light, and it will not become a line-shaped non-light-emitting defect, and the display function will not be significantly impaired. Of course, there were two breaks on the same scanning side pole. In this case, there will be no light-emitting line between the disconnected parts, so there is no effect, but the probability of such a situation occurring is very low, and the present invention is not effective even if the data side electrode is disconnected. However, the data side electrode formed of a transparent conductive film is rarely disconnected, and this does not pose a problem in practice. As described above, the thin 1[L display device of the present invention hardly causes line-shaped display defects and can be used stably for a long period of time.

示機能を失うことはなかった。When the thin-film EL display device manufactured in this way was operated for a long time, the scanning side pole was damaged by 2.3 mm due to dielectric breakdown damage.
However, because the scanning side pole was loop-shaped, line-shaped non-light-emitting defects did not occur, and the display function was not lost.
