Abstract: A display device includes a processor and a display panel for receiving observation grayscale values from the processor. The display panel includes a data driver for applying data voltages to data lines, a target pixel coupled to at least one of the data lines, and observation pixels each coupled to at least one of the data lines, and located adjacent to the target pixel. The display panel applies a first data voltage to the target pixel, when the observation grayscale values for the observation pixels exceed a reference value. The display panel applies a second data voltage to the target pixel, when at least one of the observation grayscale values does not exceed the reference value. The first data voltage and the second data voltage are different from each other.

Abstract: A display device may include a scan line, a data line, a power line, a substrate, a transistor, a light emitting device, a light shielding member, and a shielding layer. The scan line extends in a first direction and may transfer a scan signal. The data line extends in a second direction and may transfer a data signal. The power line is spaced from the data line and may transfer a driving voltage. The light emitting device is electrically connected to the transistor. The light shielding member is disposed between the substrate and the transistor. The shielding layer is electrically connected to the power line. The light shielding member includes a body member and a bridge member. The body member overlaps the transistor.
