  • Liquid crystal display panel provided with microlens array, method for manufacturing the liquid crystal display panel, and liquid crystal display device
    Patent number: 8111356
    Abstract: There is provided a liquid crystal display panel with microlenses in which deformation, peeling, and the like of an optical film are not likely to occur and which has a good displaying quality. A liquid crystal display panel according to the present invention includes: a microlens array provided on a light-incident side of a liquid crystal display panel; a support provided on the light-incident side of the liquid crystal display panel so as to surround the microlens array; and an optical film attached to the liquid crystal display panel via the support. A gap is formed between the microlens array and the optical film; at least one vent hole connecting a space outside the support and the gap is formed in the support; and, when seen perpendicularly with respect to the plane of the liquid crystal display panel, the vent hole extends in a bending manner or the vent hole extends in an oblique direction with respect to an inner face of the support.
