A liquid crystal display (LCD) panel includes an active device array substrate, an opposite substrate, a sealant, a liquid crystal layer, a black matrix, and a plurality of rough structures. The active device array substrate has a display area and a peripheral area surrounding the display area, and the liquid crystal layer and the peripheral area are surrounded by the sealant. The black matrix is disposed between the active device array substrate and the opposite substrate and distributed corresponding to the display area and the peripheral area. The rough structures are disposed on a portion of the black matrix and distributed corresponding to the peripheral area. Surface roughness of the rough structures is greater than surface roughness of the black matrix distributed corresponding to the display area.

A thin film transistor (TFT) array substrate includes a stack structure disposed to raise an extended electrode of a drain electrode of a thin film transistor. Therefore, a contact hole does need to be very deep to expose the extended electrode of the drain electrode.

Thin film transistor array substrate

A display panel includes a first substrate, a pixel array, a peripheral circuit, a first protection layer, a second protection layer, a display medium, and a second substrate. The first substrate array has a display area and a peripheral area, wherein the pixel array is disposed in the display area, the peripheral circuit is disposed in the peripheral area, and the pixel array and the peripheral circuit are electrically connected. The first protection layer is disposed on the display area and the peripheral area to cover the pixel array and the peripheral circuit. The second protection layer is at least disposed on the first protection layer within the peripheral area. Here, the second protection layer includes a color filter material layer, a black matrix material layer, a photo spacer material layer, or a combination thereof. The second substrate is disposed above the first substrate to expose the peripheral area.

An active device array substrate including a substrate, an active device array, a black matrix, a color filter, at least a pad, and at least a contact window is provided. The substrate has a display region and a periphery circuit region. The pad is disposed in the display region or the periphery circuit region and is constituted by at least one of a first conductive layer and a second conductive layer. The contact window is disposed on the pad, through which a third conductive layer is connected to the pad. The contact window is surrounded by at least two different types of light-shielding patterns, wherein each light-shielding pattern surrounds only a part of the periphery of the contact window. The light-shielding patterns are selected form at least two of the black matrix, the color filter, the first conductive layer, and the second conductive layer.
