Disclosed is a liquid crystal display panel wherein the utilization efficiency of light can be improved, while suppressing deterioration of the contrast. Specifically, a color filter (17) of a liquid crystal display panel (10) comprises: a black matrix (21) which is provided with an opening (2a); a red phosphor layer (22) and a red filter layer (23) which are arranged within the opening (21a) in a red display region (R); a green phosphor layer (24) and a green filter layer (25) which are arranged within the opening (21a) in a green display region (G); and a transparent resin layer (26) and a blue filter layer (27) which are arranged within the opening (21a) in a blue display region (B) A light exit surface of the transparent resin layer (26) is provided with a plurality of projected portions (26c), and the transparent resin layer (26) has a refractive index different from that of the blue filter layer (27), which is in contact with the light exit surface. The transparent resin layer (26) is a light diffusion layer, and is capable of increasing the viewing angle of blue light.

A liquid crystal display panel manufacturing apparatus is provided with a stage for fixing a substrate having an optical film adhered to at least one of surfaces of the substrate. The stage has a suction hole for attracting the substrate by suction. The stage has an interposition member located around a region provided with the suction hole, and the interposition member has a closed frame-like form in a plan view. A display panel manufacturing apparatus that can stably fix the substrate is provided.

A method for cutting apart a glass substrate is provided whereby scribing of the glass substrate is possible without being affected by the presence or thickness of a deposited film formed thereon and without scratching the deposited film. To treat a glass substrate having a deposited film, such as a thin film or resin film, formed on one surface thereof, there are provided a shaving device, which is a blade that removes strip-shaped portions of the deposited film to expose strip-shaped regions on the glass substrate, and a wheel cutter (14a) that forms scribed lines along the strip-shaped regions exposed on the glass substrate. The glass substrate is cut apart along the scribed lines.

A manufacturing method of a liquid crystal display panel includes: a sealant arranging step of arranging a sealant on a main surface of one of or each of two substrates to be bonded to each other; a liquid crystal dropping step of dropping liquid crystal on one of the two substrates; and a bonding step of bonding the two substrates to each other, wherein the method further includes: to be performed prior to the liquid crystal dropping step, a deaerating step of arranging in a pressure-reduced atmosphere at least a substrate on which the liquid crystal is to be dropped out of the two substrates; and, to be performed prior to the bonding step, a releasing step of releasing the pressure-reduced atmosphere by an inert gas.

A planar illumination device is provided that enhances the efficiency of use of light and its brightness while suppressing uneven brightness, that reduces an increase in the manufacturing cost and that can reduce the thickness of the planar illumination device. In this backlight device (planar illumination device) (20), in the light emitting surface (23b) of a light guide body (23), a plurality of prisms (23e) that gradually reduce an angle of incidence of light with respect to the back surface (23c) of the light guide body are provided, and, in the back surface (24a) of a low refractive index layer (24), a plurality of prisms (24b) that have the function of forwardly and totally reflecting light from LEDs (21) in an interface between the back surface of the low refractive index layer and an air layer are formed.

An light guide (12) has an indented pattern (105) on its front surface (10a) and an indented pattern (103) on its back surface (10b), and includes: a light guide plate (15) including the indented pattern (105) provided on the front surface (10a); a light distribution control part (13) including the indented pattern (103) provided on the back surface (10b); and a middle layer (14) provided between the light guide plate (15) and the light distribution control part (13), the light distribution control part (13) being less in film thickness than the light guide plate (15), and the light distribution control part (13) having a glass transition point lower than that of the light guide plate (15). This makes it possible to form indented patterns on the front surface and the back surface of an optical laminate constituted by a stack of a plurality of layers, while preventing occurrence of defects.
