An image display apparatus is provided to improve display characteristics, the apparatus including a prism and a pixel section on one side of the prism. The pixel section includes a reflective electrode and dielectrics disposed at a predetermined distance from the reflective electrode. The dielectrics are in contact with the reflective electrode if voltage is applied, and the effective refractive index changes according to the image signal. The effective refractive index of the section of the reflective electrode in contact with the dielectrics changes, and accordingly, the reflectivity of the reflective electrode changes corresponding to the image signal. The pixel section is able to regulate the surface plasmon resonance by regulating the reflective electrode, and is able to display the black state using the surface plasmon resonance. The image display apparatus provides improved contrast ratio by preventing color leaks from arising in the black state, and thus, improve display characteristics.

An OLED display device and a method of fabricating the same. The OLED display device has at least one of a common power bus line or a cathode bus line formed at a peripheral portion of the OLED display device. By forming a lower line when a gate electrode of a thin film transistor is formed, and forming an upper line connected to the lower line through a contact hole when source and drain electrodes of the thin film transistor are formed, a dual structure of lower and upper lines is formed. As such, the OLED display device can reduce the width of interconnections without a high voltage drop to thereby increase an emission area of a light emitting portion of the OLED display device.
