Abstract
An OLED device is disclosed. The OLED device includes a first substrate including a driver element and a connection electrode connected to the driver element, a second substrate including an organic light emission diode element, a contact spacer electrically connected to the connection electrode, and a sealant disposed into a cavity which is formed by the first and second substrates, the connection electrode, the organic light emission diode element, and the contact space. Herein, the sealant is bonded to the contact spacer and the connection electrode and maintains the electric connection between the contact spacer and the connection electrode. In this manner, the driver element and the organic light emission diode element are protected from external oxygen and/or moisture, and the electric connection between the connection electrode and the contact spacer is reinforced. Accordingly, the contact defect between the connection electrode and the contact spacer can be prevented and the structural strength of the OLED device can be greatly improved.
