Signal transmission circuit and display apparatus

A display apparatus, including:

• a plurality of pixel circuits;
• a circuit block which sequentially drives the plurality of pixel circuits;
• a plurality of signal paths that transmit signals outputted from circuit elements in the circuit block which respectively correspond to a final stage of the circuit block, when the pixel circuits are driven in a forward or reverse direction;
• and
• an output path formed by connecting the plurality of signal paths,
• wherein each of the plurality of signal paths includes a buffer element and a switching element which receives an output from the buffer element, the output path is formed by connecting output lines of the switching elements, there is disposed a buffer element in the output path, and wherein any of the switching elements in the plurality of signal paths is turned on according to a drive direction in the circuit block, and then a target signal is selected and outputted to the output path.
