Liquid crystal display panel and liquid crystal display device

摘要

A liquid crystal display panel includes switching elements, transparent pixel electrodes, and a transparent common electrode having a predetermined area overlapped with an upper layer of the transparent pixel electrode through an insulating film and driving liquid crystal with the transparent pixel electrode. In plane view, a shading layer covers at least one part of a conductive pattern where a light leakage occurs in front view by an alignment defect of the liquid crystal near a non-permeable conductive pattern disposed in the display region at the time of black display, and has eaves more protruding than the conductive pattern. The transparent common electrode is provided to overlap with the conductive pattern arranged to overlap with the light-shielding layer having the eaves in a side of the liquid crystal and to protrude compared with the light-shielding layer having the eaves in a planar view.

1. A liquid crystal display panel including a first substrate, a second substrate and liquid crystal interposed between the first and the second substrates,
wherein the first substrate comprises: a gate line and a source line intersecting the gate line, one of the gate line and the source line being a conductive pattern; a switching element arranged near an intersection of the gate line and the source line; a transparent pixel electrode connected to the switching element; an insulating layer formed on the transparent pixel electrode and the conductive pattern; and a transparent common electrode arranged on the insulating layer and facing to the conductive pattern through the insulating layer, the transparent common electrode including a first flat portion above the conductive pattern and extending from a first edge of the conductive pattern to a second edge of the conductive pattern, a step portion near the first edge of the conductive pattern, and a second flat portion extending from the first flat portion through the step portion, and wherein the second substrate comprises: a shielding layer overlapping at least the step portion of the transparent common electrode, and wherein an edge of the shielding layer is positioned at a portion of the second flat portion between the step portion of the transparent common electrode and an edge of the second flat portion of the transparent common electrode in a plane view.
