A display apparatus includes a gate line, a data line, and a pixel. The pixel includes first and second pixels displaying grayscales different from each other in response to a data voltage provided through the data line. The first pixel includes a first transistor including a gate electrode connected to the gate line and a first terminal connected to the data line and a first liquid crystal capacitor connected to a second terminal of the first transistor. The second pixel includes a second transistor including a gate electrode connected to the gate line and a first terminal connected to the second terminal of the first transistor and a second liquid crystal capacitor connected to a second terminal of the second transistor.

Display apparatus

A display apparatus includes first pixel groups each including first pixels disposed in a display area, and sub-pixel groups each including second pixels disposed at an outermost area of the display area and surrounding the first pixels, in which each of the second pixels has a size smaller than a size of each of the first pixels, the second pixels in each of the sub-pixel groups are respectively connected to each other in parallel.

Provided is an organic light-emitting display device including: a first pixel; a second pixel; and a common capacitor connected to the first and second pixels, wherein the first pixel comprises: a first switching transistor transmitting a first data signal in response to a first scan signal; a second switching transistor transmitting the first data signal to the common capacitor; a first storage capacitor storing a charge corresponding to the first data signal; a first driving transistor generating a driving current corresponding to the charge stored in the first storage capacitor; and a first organic light-emitting diode (OLED) emitting light corresponding to the first driving current, and wherein the second pixel comprises: a third switching transistor transmitting a second data signal in response to a second scan signal; a fourth switching transistor transmitting the second data signal to the common capacitor; a second storage capacitor storing a charge corresponding to the second data signal; a second driving transistor generating a driving current corresponding to the charge stored in the second storage capacitor; and a second organic light-emitting diode (OLED) emitting light corresponding to the second driving current.
