Abstract
A liquid crystal display device includes a pair of insulating substrates bonded to each other via a sealing material, and liquid crystal filled between a pair of the insulating substrates. A cell gap is formed so as to gradually increase from the center to an end of a display area at room temperature. According to this arrangement, it is possible to smooth out a difference in thermal expansion between the liquid crystal and the sealing material when an atmospheric temperature rises, and it is possible to prevent a cell gap from being too large in the center of the display area. Consequently, an irregular display color can be eliminated.
Claims18
A liquid crystal display device, comprising:
- a pair of insulating substrates bonded via a sealing material, and
- liquid crystal filled between said pair of insulating substrates,
- wherein the bonded pair of insulating substrates form a cell having a center and a pair of ends, and
- wherein a cell gap is formed so as to gradually and continuously increase from the center of the cell to each of the pair of ends of a display area of the cell at room temperature.
A liquid crystal display device, comprising:
- a pair of insulating substrates bonded via a sealing material, and
- liquid crystal filled between said pair of insulating substrates,
- wherein the bonded pair of insulating substrates form a cell having a center and a pair of ends, and
- wherein a cell gap is formed so as to gradually and continuously increase from the center to each of the pair of ends of a display area at room temperature, and
- wherein the cell gap is limited so that no irregular display color appears.
A liquid crystal display device, comprising:
- a pair of insulating substrates bonded via a sealing material, and
- liquid crystal filled between said pair of insulating substrates,
- wherein the bonded pair of insulating substrates crystal form a cell having a center and a pair of ends, and
- wherein a cell gap is smaller in the center than any other part of a display area at room temperature, and
- wherein a cell gap difference is set at a predetermined value between the center and at least on one of the pair of ends of said display area so that at a high temperature no display defect occurs.
