    Abstract: A display device includes a first substrate which is light transmissive and has a display region and a periphery region surrounding the display region. A light shielding portion is formed in at least the periphery region of the first substrate and has a light passing portion in the periphery region. A first scale mark portion is formed on the first substrate so as to be arranged inside the light passing portion. A second substrate overlaps the first substrate and a second scale mark portion is formed on the second substrate and forms a pair with the first scale mark portion. A sealing member seals the first and second substrates in the periphery region between the display region and the light passing portion. A dam portion is formed on the first substrate between the display region and the light passing portion.

    Abstract: A display device includes a first substrate having a light shielding layer, and a second substrate having a first metal layer, a semiconductor layer formed over the first metal layer, and a second metal layer formed over the semiconductor layer. A sealing member fixes the first substrate and the second substrate, with a first scale mark formed over the first substrate, and a second scale mark formed over the second substrate and which forms a pair with the first scale mark. The light shielding layer has a first opening portion, and the first scale mark is arranged inside the first opening portion. The second scale mark is formed of a first part of the second metal layer, and a first part of the semiconductor layer and a first part of the first metal layer are overlapped with and extend off from the first part of the second metal.

    Abstract: The displacement between a TFT substrate and a counter substrate and the cut of an alignment film caused by a columnar spacer are prevented. A liquid crystal display device includes: a TFT substrate including a scanning line extending in a first direction, a picture signal line extending in a second direction, a pixel electrode formed in a region surrounded by the scanning line and the picture signal line, and a common electrode formed as opposed to the pixel electrode through an insulating film; a counter substrate disposed as opposed to the TFT substrate and having a spacer; and a liquid crystal sandwiched between the substrates. A common metal interconnection is formed to cover the picture signal line or the scanning line, and stacked on the common electrode. A through hole is formed on the common metal interconnection. The tip end of the spacer is disposed inside the through hole.
