CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Republic of Korea Patent Application No. 10-2018-0170851, filed on Dec. 27, 2018, which is hereby incorporated by reference in its entirety.

BACKGROUND

Technical Field

The present disclosure relates to an organic light emitting display apparatus.

Discussion of the Related Art

With the advancement of an information-oriented society, a display apparatus for displaying information has been developed in various types. Recently, various display apparatuses such as a liquid crystal display (LCD) apparatus, a plasma display apparatus, and an organic light emitting display (OLED) apparatus have been utilized.

The organic light emitting display apparatus largely includes an array device and an organic light emitting device. The array device includes a switching thin film transistor connected with gate and data lines, and at least one driving thin film transistor connected with the organic light emitting device. The organic light emitting device includes an anode electrode, an organic light emitting layer and a cathode electrode which are connected with the driving thin film transistor.

However, the organic light emitting device having the above structure may have defects of abnormal driving caused by a deterioration of the thin film transistor properties and an internal short of the thin film transistor for a process of manufacturing lines and switching and driving thin film transistors.

If the thin film transistor formed in one pixel area is not driven normally, a current or voltage is not applied to the organic light emitting device connected with the thin film transistor, whereby it may cause dark spots therein. If there is a short between source and drain electrodes of the driving thin film transistor, the driving thin film transistor is not driven normally so that a voltage applied to the source electrode is directly applied to the drain electrode without being turned on/off. Thus, the pixel area to be driven is in a turning-on state, to thereby cause defects of bright spots.

Especially, the bright spots may be clearly visible to a user, to thereby deteriorate a picture quality. Thus, even though only one spot occurs in a front surface of a display area, it becomes a defective display device, whereby it cannot be used for a final product.

SUMMARY
