Display device with light-blocking coupling wiring

A display panel comprising:

• an array substrate comprising
• a plurality of pixel electrodes in a display region, and
• common potential wiring outside the display region;
• a counter substrate comprising
• a light-blocking layer formed of a conductive material, and
• a common electrode stacked on the light-blocking layer;
• a liquid crystal layer between the array substrate and the counter substrate;
• and
• an inter-substrate conductor,
• wherein
• the light-blocking layer comprises
• a first portion having a grid shape in the display region, and
• a second portion having a linear shape and disposed outside the display region,
• the second portion has
• a first end connected to the first portion, and
• a second end opposed to the first end, the second end having an annular body,
• the common potential wiring has a mesh shape and is overlapped by the inter-substrate conductor, and
• the common potential wiring having the mesh shape is connected to the annular body of the second portion via the inter-substrate conductor, and overlaps an opening of the annular body of the second portion.
