Abstract
A pair of substrates are opposed to each other and the peripheral portions thereof are sealed by a sealing member. A part of the sealing member is opened so as to constitute a liquid crystal injection hole. A groove for introducing a liquid crystal is provided on the inner surface of at least one of the substrates in such a manner as to lead from the injection hole to the inner surface of the cell.
