Description
Technical field
The present invention relates to liquid crystal display devices and polarizer.Specifically, it is related to mitigate the liquid of the generation of iris color spot
Crystal device and polarizer.
Background technology
The polarizer used in liquid crystal display device (LCD) is usually the structure that polarizer is clamped with 2 polaroid protective films
Into the polarizer is obtained from being infected with iodine on polyvinyl alcohol (PVA) etc., as polaroid protective film, usually using three
Cellulose acetate (TAC) film.In recent years, attend by the slimming of LCD, it is desirable that polarizer it is thin layer.But if make thus
The thickness of TAC film used as protective film is thinning, then can not obtain enough mechanical strengths, in addition, it may occur that penetrability
The problem of deterioration.In addition, TAC film is very expensive, as cheap replacement raw material, although proposing polyester film (patent
Document 1~3), but there are problems that iris color spot.
In the case where the one-sided configuration of polarizer has the oriented polyester films of birefringence, from back light unit or polarization
The rectilinearly polarized light that piece projects polarization state when passing through polyester film can change.The light of transmission is according to the double of oriented polyester films
It reflects product, that is, retardation with thickness and shows distinctive interference colours.Therefore, if not connected using cold-cathode tube, thermionic-cathode tube etc.
Continuous luminescent spectrum then shows different transmitted intensities according to wavelength and forms iris color spot (reference as light source：The
15 micro-optics proceedings, the 30th~31).
As for solution to the problems described above, it is proposed that using have as white light-emitting diode it is continuous and
The white light source of wider luminescent spectrum uses the oriented polyester films conduct with certain retardation as back light
Polaroid protective film (patent document 4).For white light-emitting diode, there is continuous and wider hair in visible light region
Light spectrum.Therefore, it is proposed to when being conceived to the envelope shape of interference color spectrum of the transmitted light based on transmission birefringence body, lead to

In the case that oriented film is as polaroid protective film, iris color spot is also had no from the surface of pellicular front, but from oblique
Sometimes iris color spot is observed during observation, it is therefore desirable to pay attention to.
When the film forming condition of polyester film is specifically described, longitudinal drawing temperature, transverse drawing temperature are preferably 80
~130 DEG C, particularly preferably 90~120 DEG C.When making thin film alignment in a manner that slow axis becomes TD directions, longitudinal stretching multiplying power is excellent

Rate, draft temperature, film thickness carry out.For example, stretching ratio is higher, draft temperature is lower, the thickness of film is thicker, more
It is easy to get high retardation.On the contrary, stretching ratio is lower, draft temperature is higher, the thickness of film is thinner, more it is easy to get low
Retardation.But if thickening the thickness of film, thickness direction phase difference easily becomes larger.Therefore, it is desirable that film thickness

The film of 15 μm of thickness is less than, the retardation of more than 1500nm can be also obtained in principle.But in this case, it is thin
The anisotropy of the mechanical characteristic of film becomes notable, becomes easily to crack, breakage etc., the practicability as industrial materials is shown
Writing reduces.The lower limit of particularly preferred thickness is 25 μm.On the other hand, if the upper limit of the thickness of polaroid protective film is more than 300 μ
M, then the thickness of polarizer will become blocked up, not preferably.From the viewpoint of the practicability as polaroid protective film, thickness
The upper limit be preferably 200 μm.The upper limit of particularly preferred thickness is 100 μm with common TAC film equal extent.In order to upper
It states in thickness range and also controls retardation for the scope of the present invention, the polyester used as film substrate is preferably poly- to benzene two

Ground is compounded, and is preferably set to the concentration of 5~30 mass %.As the condition for making masterbatch, it is preferable to use mixing extruder, squeezing out
Temperature is squeezes out 1~15 minute more than the fusing point of polyester raw material and at less than 290 DEG C of temperature.At 290 DEG C or more, ultraviolet light is inhaled
The weightless increase of agent is received, in addition, the viscosity reduction of masterbatch becomes larger.When finding time less than 1 minute, ultra-violet absorber becomes
It is difficult to uniformly mix.At this point it is possible to it is added as needed on stabilizer, hue adjustment agent, antistatic agent.
Additionally, it is preferred that polyester film to be made at least 3 layers or more of multilayered structure, and purple is added in the middle layer of film
Ultraviolet absorbers.The film for the 3-tier architecture that middle layer contains ultra-violet absorber can specifically be made as follows.Using as
