摘要： A display apparatus includes a first pixel circuit and a second pixel circuit. The first pixel circuit includes a first driving transistor and a first storage capacitor having a first lower storage electrode connected to a gate of the first driving transistor and a first upper storage electrode overlapping the first lower storage electrode. The second pixel circuit includes a second driving transistor and a second storage capacitor including a second lower storage electrode connected to a gate of the second driving transistor and a second upper storage electrode overlapping the second lower storage electrode. A second overlapping area of the second lower storage electrode and the second upper storage electrode is about twice to about four times a first overlapping area of the first lower storage electrode and the first upper storage electrode.

摘要： A method of inspecting a display panel, which is capable of substantially minimizing a color difference of a display panel according to a viewing angle, includes: setting a reference area having a center point on a chromaticity diagram; emitting a white light on the display panel; measuring first color coordinates of a target point of the display panel at a first viewing angle; measuring second color coordinates of the target point at a second viewing angle; calculating a difference value between the first color coordinates and the second color coordinates; converting the difference value into target polar coordinates with the center point as an origin; and determining whether the target polar coordinates are within the reference area.

摘要： A chemical liquid supply assembly may include a chemical liquid supply line for providing chemical liquid to ink jet heads. The chemical liquid supply assembly may include a main line having a first diameter and extending in a first direction, branched lines divided from the main line in a second direction perpendicular to the first direction and connected to the ink jet heads, each of the branched line having a second diameter smaller than the first diameter, and a discharge line connected to one end portion of the main line such that bubbles generated in the chemical liquid supply line are discharged out of the chemical liquid supply line while the chemical liquid supply assembly provides the chemical liquid to the ink jet heads.
