Abstract
A display apparatus includes a counter substrate, an array substrate placed opposite the counter substrate, a liquid crystal sandwiched between the counter substrate and the array substrate, and a columnar spacer placed on a surface of the counter substrate facing the array substrate so as to maintain a gap between the counter substrate and the array substrate. A step portion with a height of 0.3 μm or smaller is placed on the part of the array substrate which is opposite the columnar spacer or on the top face of the columnar spacer, and the proportion of a highest level of the step portion to the top face of the columnar spacer is ½ or smaller.
Claims17
A display apparatus comprising:
- a first substrate;
- a second substrate placed opposite the first substrate;
- a display material placed between the first substrate and the second substrate;
- a columnar spacer placed above a surface of the first substrate facing the second substrate to maintain a gap between the first substrate and the second substrate;
- and
- a step portion placed above a part of the second substrate opposite the columnar spacer or on a top face of the columnar spacer with a height of 0.3 μm or smaller with a proportion of a highest level of the step portion to the top face of the columnar spacer being ½ or smaller.
A method of manufacturing a display apparatus including a display material placed between a first substrate and a second substrate, comprising:
- forming a columnar spacer above the first substrate;
- forming a step portion with a height of 0.3 μm or smaller by forming a plurality of thin films above the second substrate;
- and
- attaching the first substrate and the second substrate through a sealing material by placing a surface of the first substrate having the columnar spacer and a surface of the second substrate having the step portion opposite each other with a proportion of a highest level of the step portion to a top face of the columnar spacer being ½ or smaller.
A method of manufacturing a display apparatus including a display material placed between a first substrate and a second substrate, comprising:
- forming a columnar spacer having a protrusion with a height of 0.3 μm or smaller above the first substrate with a proportion of the protrusion to a top face of the columnar spacer being ½ or smaller;
- and
- attaching the first substrate and the second substrate through a sealing material by placing the second substrate opposite a surface of the first substrate having the columnar spacer.
