Claim Text:
1. A liquid crystal display device comprising: a first substrate having a plurality of scanning signal lines extending in the X direction and parallel to one another in the Y direction and a plurality of image signal lines extending in the Y direction and parallel to one another in the X direction formed thereover; a second substrate opposed to the first substrate through a liquid crystal layer; a display area surrounded by the scanning signal lines and the image signal lines in which pixels are arranged in a matrix, wherein the first substrate and the second substrate are fixed by means of a seal material formed along the marginal part of the second substrate, the liquid crystal layer is sealed between the first substrate and the second substrate, the first substrate is larger in size than the second substrate, and a connection terminal is formed in an exposed area not opposed to the second substrate of the first substrate; a drive circuit for generating a scanning signal and/or an image signal, which is formed in the peripheral part of the display area and formed from a thin film transistor formed in the same step as the formation of the pixels; control signal lines for electrically coupling the connection terminal to the drive circuit, and wherein a groove is formed in an area between a plurality of the thin film transistors in the formation area of the drive circuit and reaches the formation area of the control signal lines, the groove has a bent area reaching the formation area of the control signal lines, and the bottom part of the groove formed closer to the display area than the bent area has a projecting area projecting toward the liquid crystal surface side.
