Abstract: A display panel includes a plurality of pixel areas and at least one inspection area. An incident light is irradiated onto an inspection pattern disposed in the inspection area and a reflection light reflected by the inspection pattern is detected. An optical critical dimension of the inspection pattern is calculated from the reflection light, and a dimension of a pixel pattern disposed in each pixel area is calculated from the optical critical dimension of the inspection pattern. Accordingly, the dimension of the pixel pattern may be indirectly measured from the inspection pattern.
Abstract translation: 显示面板包括多个像素区域和至少一个检查区域。 将入射光照射到设置在检查区域中的检查图案，并检测由检查图案反射的反射光。 根据反射光计算检查图案的光临界尺寸，并且从检查图案的光临界尺寸计算设置在每个像素区域中的像素图案的尺寸。 因此，可以从检查图案间接测量像素图案的尺寸。
