ABSTRACT:
An electrode plate including a substrate, a plurality of stripe-shaped electrodes with gaps therebetween, and a flattening layer filling the gaps is produced through a process including the steps of: supplying a flowable polymeric material to a part of a surface of a smooth plate or substrate; applying the smooth plate and the substrate to each other so as to sandwich the polymeric material therebetween to provide a laminate; pressing the smooth plate and the substrate to each other, the pressing step including a preliminary pressure step wherein a pressed portion is moved from a first side of the laminate to a second side parallel to the first side under application of a first pressure and a main pressure step wherein a pressed portion is moved from one side of the laminate to the other side parallel to the one side under application of a second pressure larger than the first pressure to extend the polymeric material over at least a region including the stripe-shaped electrodes; curing the polymeric material by irradiation with a light to form a flattening layer; and removing the smooth plate from the laminate.
