Abstract

According to an aspect, a display device includes: a first substrate; a second substrate arranged opposite to the first substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a plurality of pixels arranged in a matrix on the first substrate; a first scan line arranged between a first row of the pixels and a second row of the pixels adjacent to the first row; a second scan line arranged between the second row of the pixels and the first scan line; and a spacer for maintaining a gap between the first substrate and the second substrate. A first area on which the spacer is disposed overlaps at least part of a second area partitioned by the first scan line and the second scan line.

Claims (47)

1. A display device comprising:

a first substrate;

a second substrate arranged opposite to the first substrate;

a liquid crystal layer interposed between the first substrate and the second substrate;

a plurality of pixels arranged in a matrix on the first substrate;

a first scan line arranged between a first row of the pixels and a second row of the pixels adjacent to the first row;

a second scan line arranged between the second row of the pixels and the first scan line;

an insulating film provided over the first scan line and the second scan line; and

a spacer for maintaining a gap between the first substrate and the second substrate, wherein

a first area on which the spacer is disposed overlaps at least part of a second area partitioned by the first scan line and the second scan line,

the spacer is disposed on the insulating film, and

a curvature of the surface of the insulating film in the first area is smaller than that of the surface of the insulating film outside the first area.

2. The display device according to claim 1 , further comprising an element for each pixel scanned by the first scan line, wherein

the insulating film covers the element, and

a curvature of the surface of the insulating film in the first area is smaller than that of the surface of the insulating film above the element in the vertical direction with respect to the first substrate.

3. A display device comprising:

a first substrate;

a second substrate arranged opposite to the first substrate;

a liquid crystal layer interposed between the first substrate and the second substrate;

a plurality of pixels arranged in a matrix on the first substrate;

a first data line arranged between a first column of the pixels and a second column of the pixels adjacent to the first column;

a second data line arranged between the second column of the pixels and the first data line;

an insulating film provided over the first data line and the second data line; and

a spacer for maintaining a gap between the first substrate and the second substrate, wherein

a first area on which the spacer is disposed overlaps at least part of a second area partitioned by the first data line and the second data line,

the spacer is disposed on the insulating film, and

a curvature of the surface of the insulating film in the first area is smaller than that of the surface of the insulating film outside the first area.

4. The display device according to claim 3 , further comprising an element for each pixel scanned by the first scan line, wherein

the insulating film covers the element, and

a curvature of the surface of the insulating film in the first area is smaller than that of the surface of the insulating film above the element in the vertical direction with respect to the first substrate.

5. A display device comprising:

a first substrate;

a second substrate arranged opposite to the first substrate;

a liquid crystal layer interposed between the first substrate and the second substrate;

a plurality of pixels arranged in a matrix on the first substrate;

a first scan line arranged between a first row of the pixels and a second row of the pixels adjacent to the first row;

a second scan line arranged between the second row of the pixels and the first scan line;

a first data line arranged between a first column of the pixels and a second column of the pixels adjacent to the first column;

a second data line arranged between the second column of the pixels and the first data line; and

a spacer for maintaining a gap between the first substrate and the second substrate, wherein

a first area on which the spacer is disposed overlaps at least part of a third area partitioned by the first scan line, the second scan line, the first data line, and the second data line.

6. The display device according to claim 5 , further comprising an insulating film provided over the first scan line, the second scan line, the first data line, and the second data line, wherein

the spacer is disposed on the insulating film, and

a curvature of the surface of the insulating film in the first area is smaller than that of the surface of the insulating film outside the first area.

7. The display device according to claim 6 , further comprising an element for each pixel scanned by the first scan line, wherein

the insulating film covers the element, and

a curvature of the surface of the insulating film in the first area is smaller than that of the surface of the insulating film above the element in the vertical direction with respect to the first substrate.
