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.
