• a plurality of pixels arranged in an active area in the first area;
• and
• a mount portion including a plurality of pads to which either a driver IC or a flexible printed circuit board is to be connected;
• wherein
• the first area of the first substrate is an area where the second substrate opposes the first substrate,
• the second area of the first substrate is an area where the first substrate is exposed from the second substrate,
• the first substrate end is a boundary between the first area and the second area,
• the organic insulating film includes a groove and an opening,
• the groove is formed outside of the active area in the first area,
• the opening is formed at a region where the mount portion is arranged in the second area, and
• the organic insulating film surrounds the mount portion in the second area.
