Title: LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
The present invention provides a horizontal-electric-field-mode liquid crystal display panel that has excellent visibility in a bright place and suppresses light from leaking at the edges of an active region. The liquid crystal display panel according to the present invention has, from the observation surface side to the rear surface side in the following order, a first polarization plate, a first λ/4 layer, a first substrate, a second λ/4 layer, a liquid crystal layer, a second substrate, and a second polarization plate, wherein in an active region, the first substrate has a plurality of color filter layers including an edge color filter layer located at the edge of the active region, and in a non-active region, the first substrate has, from the observation surface side to the rear surface side in the following order, a black matrix and a dummy color filter layer which overlaps the black matrix and which is adjacent to the edge color filter, a step of at most 1.2 μm in height is provided between the surface of the edge color filter layer and the surface of the dummy color filter layer, and the second λ/4 layer overlaps a boundary between the edge color filter layer and the dummy color filter layer.
