The present invention relates to a display panel, and more particularly to a liquid crystal display panel.

In recent years, as the field of application has expanded, not only the demand for properties such as thinness, narrow bezel, and high image quality of display devices has been improved, but also the demand for changes in the shape of the display region of the display panel in the display device has been increasing. The display area of a display device conventionally applied to electronic devices such as televisions, personal computers, and mobile phones is almost rectangular in shape, but is rectangular in shape for devices such as an in-vehicle instrument panel, an entertainment display device, and a wearable display device. The appearance has been unable to meet the needs of users. Accordingly, such devices are typically equipped with display panels having non-rectangular display areas, such as circular or other shaped display areas.

Therefore, for a display panel having a non-rectangular display area, how to effectively reduce the edge color mismatch is an important subject that must be overcome.

The edge pixels at least partially overlap with the peripheral light shielding layer, wherein each edge pixel includes a first edge pixel electrode, a second edge pixel electrode, and a third edge pixel electrode, wherein the first edge pixel electrodes The pattern of at least one of the second edge pixel electrodes and the third edge pixel electrodes is different from the first standard pixel electrodes, the second standard pixel electrodes, and the third standard pixels A pattern of at least one of the electrodes. The second substrate is located opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate.

In the liquid crystal display panel of the present invention, at least one of the first edge pixel electrode, the second edge pixel electrode, and the third edge pixel electrode in the edge pixel at least partially overlapping the peripheral light shielding layer is transmitted. The pattern of the person is different from the pattern of at least one of the first standard pixel electrode, the second standard pixel electrode, and the third standard pixel electrode in the standard pixel that does not overlap the peripheral light shielding layer, thereby being effective The problem of edge color mismatch in the liquid crystal display panel is reduced, thereby improving the aesthetics and visual comfort of the liquid crystal display panel.
