A mother substrate for a display panel and a display panel using the same are disclosed. A mother substrate for a display panel includes a conductive ring disposed in a non-display area outside the display area and surrounding each of the display areas, and one or more dummy pixel driving circuits disposed in a non-display area outside the display area. An electrostatic discharge (ESD) prevention structure inside the dummy pixel driving circuit can prevent defects of display panels due to ESD occurring in the manufacturing process of the display panel.

Mother substrate and display panel using the same

A mother substrate for a display panel and a display panel using the same are disclosed. The mother substrate comprises a plurality of display area including a plurality of light-emitting areas configured to receive light-emitting elements, a plurality of wirings, and a plurality of pads connected to the plurality of wirings; a conductive ring in a non-display area that surrounds the display area such that each of the display areas is surrounded by the conductive ring and electrically connected to the pads; a photoresist pattern covering the plurality of display areas and the non-display area; and a first metal layer covering the photoresist pattern. The conductive ring includes an electrostatic blocking area.

Mother substrate for display panel, display panel using the same

A display device including a liquid crystal layer is provided. The liquid crystal layer may be disposed between a first substrate and a second substrate. The liquid crystal layer overlapping with a display area may be surrounded by a seal member disposed on a bezel, which is disposed outside the display area. A black matrix between the liquid crystal layer and the second substrate may include first openings in the display area and at least one second opening disposed between the display area and the seal member. A dummy color pattern between the first substrate and the liquid crystal layer may include a region overlapping with the second opening of the black matrix and a region disposed between the display area and the second opening.

Display device

An IPS mode LCD device with an improved aperture ratio is disclosed. The IPS mode LCD device includes: gate lines and data lines configured to cross each other and to define first and second pixel regions arranged to alternate with each other; a thin film transistor formed at each intersection of the gate and data lines and configured to include a source electrode extended from the data line, a drain electrode separated from the source electrode, and a gate electrode extended from the gate line; a pixel electrode configured to include a pixel electrode lead portion connected to the drain electrode, a pixel electrode connection bar extended from the pixel electrode lead portion, and a plurality of pixel electrode protrusions extended from the pixel electrode connection bar; common lines arranged to be separated parallel to the gate lines; and a common electrode configured to include a common electrode connection bar connected to the common line, and a plurality of common electrode protrusions extended from the common electrode connection bar and arranged to alternate with the pixel electrode protrusions. At least one of the first and second pixel regions is configured to include upper and lower portions in which the pixel electrode protrusions and the common electrode protrusions are arranged in different numbers.
