Abstract: The present disclosure relates to an electronic apparatus. The electronic apparatus includes a base substrate, a first sensing electrode, and a second sensing electrode. A hole is defined through the base substrate. The first sensing electrode includes first sensing patterns and first connection patterns, which are arranged in a first direction. The second sensing electrode includes second sensing patterns and second connection patterns, which are arranged in the first direction. One first connection pattern and one second connection pattern are spaced apart from each other in a second direction with the hole defined therebetween. A first distance in the second direction between the one first connection pattern and the one second connection pattern is greater than a second distance in the second direction between another first connection pattern and another second connection pattern.

Abstract: An input sensing unit includes a first sensing electrode, a second sensing electrode insulated from the first sensing electrode, a first sensing line connected to one end of the first sensing electrode, a second sensing line connected to the other end of the first sensing electrode, a third sensing line connected to one end of the second sensing electrode, a first bridge pattern connecting the first sensing line and the second sensing line, a second bridge pattern substantially parallel to the first bridge pattern, and a pad connected to the second bridge pattern. The first bridge pattern extends in a first direction and overlaps the first sensing electrode in the first direction, and the pad is disposed closer to the second bridge pattern than the first bridge pattern. Thus, the input sensing unit has improved reliability.
