Abstract
The present invention provides a liquid crystal display panel which can prevent a leak path of a sealing material when liquid crystal is brought into contact with an uncured sealing material in a sealing step and a manufacturing method thereof. In a liquid crystal display panel which forms a display region by providing liquid crystal in a gap defined between one substrate and another substrate, a weir which is continuously formed so as to surround the display region and a sealing material which is arranged to cover the weir are arranged on a surface of one substrate.
Claims13
A liquid crystal display panel which forms a display region by providing liquid crystal in a gap defined between one substrate and another substrate, wherein
- a weir which is continuously formed so as to surround the display region and a sealing material which is arranged to cover the weir are arranged on a surface of one substrate.
A manufacturing method of a liquid crystal display panel which fills liquid crystal into a gap defined between one substrate and another substrate and seals both substrates using a sealing material which is circumferentially applied outside a display region tracing a profile of the display region, wherein
- the manufacturing method comprising the steps of
- forming a continuous weir in a state that the weir surrounds the display region on one substrate;
- arranging spacers on one substrate or another substrate;
- applying a sealing material to one substrate in a frame shape in a state that the sealing material covers the formed weir;
- dripping the liquid crystal into the inside of the frame-shaped sealing material,
- aligning one substrate with another substrate in a reduced-pressure atmosphere and adhering one substrate and another substrate to each other while defining a gap therebetween;
- and
- curing the sealing material between one substrate and another substrate after the completion of adhesion of one substrate and another substrate.
