Abstract: A liquid crystal display device includes a first substrate, a second substrate facing the first substrate, a dual passivation layer disposed between the first substrate and the second substrate. The dual passivation layer includes a first passivation layer and a second passivation layer. A refractive index of the first passivation layer is different from a refractive index of the second passivation layer.

Abstract: A display device includes a pixel array disposed in a display area, a connection pad disposed in a pad area, and a transfer wiring electrically connected to the connection pad to transfer a signal to the pixel array. The pixel array includes a light-emitting element including a first electrode including a multi-layered structure including a metal layer and a metal oxide layer, an organic light-emitting layer disposed on the first electrode, and a second electrode disposed on the organic light-emitting layer. The connection pad includes an upper pad conductive layer having a single-layered structure including a metal oxide.

Abstract: A display apparatus includes a display panel, a timing controller, a data driver and a voltage generator. The display panel includes a switching element, a pixel electrode connected to the switching element, a common electrode, a storage electrode and a pixel electrode. The timing controller processes input image data according to a variable frame rate and generates a data signal having a variable frame length. The data driver converts the data signal into a data voltage and outputs the data voltage to the pixel electrode. The voltage generator may apply a common voltage to the common electrode and a storage voltage greater than the common voltage to the storage electrode, and/or apply the common voltage varied according to a grayscale value of the input image data. Embodiments may reduce or obviate a display defect caused by luminance differences between frames displayed at different frame rates.
