Abstract: To provide a structure and a manufacturing method which can manufacture, at a low cost and with good yield, a liquid crystal display panel having a lenticular lens and a substrate formed in a unified manner. When forming a lenticular lens onto a mother CF substrate by using a wet etching method, substrates are dipped into an etching solution while being raised up in such a manner that the length direction of slit openings of a mask is aligned with a vertical direction and an area having no mask pattern comes on a bottom side. With this, the residuals generated due to glass impurities can be drained towards the lower side along the lenticular lens shape to be discharged to the flat area, which makes it possible to suppress deterioration in the etching processed shape.
