摘要： PROBLEM TO BE SOLVED: To improve the utilizing efficiency of contrast and light source light by mutually facing the rectangular parts of rectangular prism and forming a cross shape with faces sandwiching the rectangular prism. SOLUTION: As a color synthesizing means, the perpendicular parts of four rectangular prisms are mutually faced, the cross shape is formed between the faces sandwiching the rectangular part, and an optical prism is used for arranging two kinds of different color light selective reflecting layers so as to form the cross shape along the inner faces forming this cross shape. White light emitted from a light source 50 is collimated by a condenser lens 51, made incident to a 1st cube prism 52 and separated into three colors of red, blue and green. The decomposed light is made incident to a transmissive light value 54 after its direction is bent by a mirror 53. The light value is arranged at a position to form the image with a projection lens 56. A 2nd cube prism 55 synthesizes the transmission of the light valve through the color synthesizing prism.

摘要： PURPOSE:To make a device compact and light in weight by making the distance between the centers of the optical axes of a first mirror and a third mirror twice as long as the distance between the centers of the optical axes of the first mirror and a fourth mirror. CONSTITUTION:Blue color light is spectrally split by the blue-reflecting mirror 25 and transmitted through the blur-reflecting mirror 28 so as to illuminate a blur-display panel 31. Red color light is spectrally split by the red-reflecting mirror 26 so as to illuminate a red-display panel 32. A green-display panel 33 is illuminated with the left green color light. A video displayed on the panel 33 is transmitted through the green-reflecting mirror 27 and the green-reflecting mirror 30 and it arrives at a projection lens 13. A video displayed on the panel 32 is transmitted through the red-reflecting mirror 29 and it arrives at the lens 13. A video displayed on the panel 31 is transmitted through the mirrors 29 and 30 and its arrives at the lens 13. Then, the distance of a straight line connecting the mirrors 25, 26 and 27 is set so as to be twice as long as the distance of a straight line connecting the mirrors 25 and 28.

The UV curing type resin 106 as the sealing member is constituted of at least one kind of a reactive diluent selected from the prepolymer or oligomer of the epoxy (meth)acrylate and a (meth)acryl monomer and a radical generation type photopolymn. initiator. The liquid crystal display panel having the sealing member which allows the low-temp. and large-quantity treatment and does not exert adverse influence on the reliability and display characteristics of the liquid crystal is thereby obtd.

摘要： PURPOSE:To remove coloring of half tone display by optimizing the arrangement of TN liquid crystal light bulb polarizing plates to red, green and blue light beams. CONSTITUTION:A polarizing plate on the projection side is arranged in common with red, green and blue beams so that the absorbing axis 6 of the polarizing plate is almost parallel with the orientation axis 5 of liquid crystal molecules on a projection substrate. On the other hand, an incident polarizing plate is arranged so that the transmission axes for red, green and blue beams are set up like 1-3 and angular differences obtained by subtracting the twisted angles of the TN liquid crystal in respective TN liquid crystal light bulbs from angles formed by the transmission axes 1-3 and the absorbing axis 6 of the projecting polarizing plate in the twisted direction of the liquid crystal molecules are reduced in the order of red, green and blue. Consequently, the voltage/ transmissivity curves of red, green and blue components are made almost coincide with each other, so that colorless excellent half tone display can be obtained.

摘要： PURPOSE:To eliminate influences upon display pictures of light scattering, light transmission, and light absorption due to gap materials by using a light-reactive organic resin to selectively arrange gap materials on a light shielding layer in a liquid crystal display panel. CONSTITUTION:A solution prepared by dispersing ball-shaped gap materials, columnar gap materials 3, or the like in a resin hardened by ultraviolet rays or a photoresist is applied on a counter substrate 1 by roll coating, spin coating, printing, or the like, and this substrate is subjected to prebaking and is exposed through a prescribed exposure mask and is developed and printed. By this stage, gap materials 3 are selectively adhered onto a light shielding layer 2. An organic high polymer layer or an inorganic high polymer layer is formed on a pair of obtained substrates and is subjected to the rubbing treatment, and a twisted nematic liquid crystal is enclosed in vacuum after pressuring and adhering seal peripheries to obtain an active matrix liquid crystal panel. Thus, an apparent aperture rate is improved to obtain pictures which have a high contrast ratio and are superior in color purity.
