Manufacture method of display faceplate with microlens array, display device and exposure device

Abstract

The present invention is a method for manufacturing a display panel (100) having a display panel (101) and a plurality of microlenses (107) arranged on the light incident side of the display panel, comprising (a) preparing a plurality of microlenses (107) arranged in a matrix The process of the pixel display panel, that is, preparing a plurality of pixels each including a first pixel (104B) that transmits a first color light and a second pixel 104R (104G) that transmits a second color light different from the first color light A process of a display panel of a plurality of pixels; (b) a process of forming a photocurable material layer (105) on one of a pair of main surfaces opposite to each other of the display panel; (c) through the display panel The process of exposing the photocurable material layer, that is, the process of curing at least a part of the photocurable material layer with light transmitted through at least the first pixel; (d) removing the exposed photocurable material layer (105') The process of forming a plurality of microlenses (107) on the unhardened portion.

Description

technical field [0001] The invention relates to a manufacturing method, a display device and an exposure device of a display panel with a microlens array. Background technique [0002] Non-self-illuminating display devices represented by liquid crystal display devices usually use driving signals to change the transmittance (or reflectance) of the display panel, and modulate the intensity of light emitted by the light source that irradiates the display panel to display images or text . Such display devices include direct-view display devices that directly observe images displayed on a display panel, and projection display devices (projectors) that enlarge and project images displayed on a display panel onto a screen using a projection lens. In addition, as non-self-luminous display panels other than liquid crystal display panels, electronic display panels, electrophoretic display panels, toner display panels, PLZT display panels, and the like are known. Currently, liquid cr...

Problems solved by technology

[0008] The transflective liquid crystal display device uses the light from the backlight of the liquid crystal display panel to display under dark lighting, and reflects the surrounding light under bright lighting. High-contrast display is achieved, but brightness decreases when the aperture ratio of the transmissive area is reduced

[0009] In particular, in direct-view liquid crystal display devices or single-panel projectors that utilize light absorption by color filters for color display, the utilization efficiency of light (that is, brightness) further decreases.
