PURPOSE:To allow the correction of the luminescent point picture element of a high- brightness liquid crystal display device made of pasted micro lens array substrates by forming a recessed machined section near the surface of a transparent substrate along the irradiation passage of a picture element having a luminescent point defect. CONSTITUTION:A quadrangular pyramid or conical recess 18 narrowed toward the bottom thereof is formed on the surface of a glass substrate at such a position as corresponding to a luminescent point picture element, or a luminescent point correction section 16. In addition, rough surfaces 17A and 17B are formed on the bottom and side of the recess 18, thereby dimming or shading illumination light passing through the luminescent point picture element. The section 16 is positioned on the same irradiation path as the luminescent point picture element generating a luminescent point for irradiated light. Furthermore, regarding a pair of pasted substrates 2 and 27, illumination light 40 from a light source is selected at a position near the surface of the illuminated glass substrate 2. According to this construction, a dimming effect due to incident light diffusion becomes high at the recess 18, and a light quantity passing through the luminescent point picture element can be made to match a surrounding normal picture element by selecting roughening level. |
