Abstract: A display device includes a display panel including first to fourth panel pads and a connection board including first to fourth connection board pads coupled to the first to fourth pads, respectively. The first and second panel pads are electrically connected to each other, and the third and fourth panel pads are electrically connected to each other. The connection board includes a driving circuit which generates a first test result signal based on a first panel test signal transmitted to the first connection board pad and a first panel feedback signal received from the second connection board pad, generates a second test result signal based on a second panel test signal transmitted to the third connection board pad and a second panel feedback signal received from the fourth connection board pad, and sequentially outputs the first and second test result signals as a test result signal.

Abstract: A display device includes a first display substrate including a display area and a non-display area, a second display substrate facing the first display substrate and including an end portion corresponding to the non-display area and extending along a first direction; a connection circuit board connected to the first display substrate at the non-display area thereof and disposed adjacent to the end portion of the second display substrate; and a first spacer and a second spacer each on the end portion of the second display substrate, and spaced apart from each other along the first direction to define a space therebetween. Along a second direction which crosses the first direction, a central portion of the connection circuit board connected to the first display substrate faces the space between the first spacer and the second spacer on the second display substrate.

Abstract: A display device includes a display panel including pixels disposed at rows and columns, first data lines respectively disposed at the columns, and second data lines respectively disposed at the columns, a first data driver connected to the first data lines, and a second data driver connected to the second data lines. A first portion of the pixels are connected to the first data lines, and a second portion of the pixels are connected to the second data lines. The first data driver provides first gray voltages corresponding to a first gamma curve to the first portion of the pixels through the first data lines, and the second data driver provides second gray voltages corresponding to a second gamma curve different from the first gamma curve to the second portion of the pixels through the second data lines.
